Core i7 Entry

With the i7 processors at the top of every performance comparison, many readers are interested in building a new Core i7 system. However, much of the i7 architecture is unique compared to current computer architectures, with a new socket 1366 and triple-channel DDR3 memory. That means i7 buyers will likely be buying more components than normal for the move to i7. In fact it is not unreasonable to expect a complete new system build, or at least the bulk of a complete system build, when you decide to move up to Core i7.

The question then is what is the absolute minimum you can spend and still get into a decent performing i7 system? In our System Buyers Guide: $1000 to $2000 a balanced i7 system with the cheapest Core i7 CPU managed to squeeze in at just under $2000. In the short time since that guide was published many prices have dropped, new drivers are available, and there are more options available for a Core i7 system. The goal is also a bit more modest in this Core i7 Entry system. The task was to put together a complete i7 system at near bare bones pricing.

In almost every category a lower performing and lower priced option is possible, but it makes little sense to build an i7 system and saddle it with last generation's midrange video card for example. For that reason the video choice was a Radeon 4870 1GB, which many consider the minimum for a serious gaming rig. Where the lower-priced options make just a small difference in performance we chose lower price, but where it really mattered in total system performance the better performing choice was made.

The i7 920 is the lowest priced Intel Core i7 you can currently buy. The other two choices are in the $600 to $1000 price range. Don't assume, however, that the 920 is not a powerful processor. The i7 920 is 30% faster in some tests than a Core 2 Quad, and then you find you can also overclock this 2.66GHz CPU to 3.6GHz to 4GHz with careful tweaking and better cooling. You will certainly be very happy with Core i7 base performance, but if you are interested in overclocking you will be even happier with this new CPU.

The Gigabyte GA-EX58-UD3R has the distinction of being the lowest priced X58 chipset motherboard you can currently buy. Others will join that sub-$200 price point soon to provide more X58 value choices. You probably also noticed that Gigabyte is trying to get as much mileage as possible from their UD3R designation, holding on to a good name as much as possible.

Since this system goal is the lowest priced Core i7 system, we stuck with the retail Intel HSF that comes with the CPU. It works fine with the Core i7 at stock speeds, even though it runs hotter than a similar Intel HSF on Core 2 chips. In the past an Intel retail HSF would be a guarantee of at least midrange overclocking, but the Core i7 runs hotter and you will not get much of an overclock with the Intel HSF. If you plan to overclock you will definitely need a third party HSF, like the Vigor Monsoon III or the Thermalright Ultra-120 eXtreme-1366.

In the Core i7 System in the $1000 to $2000 System Guide, the problems with ATI drivers on Core i7 were discussed. Since then driver releases from ATI are going in the right direction. There is also the price difference, with the capable 4870 1GB some $120 less than the now lower-priced NVIDIA GTX 280. There is also the fact that the Gigabyte GA-EX58-UD3R supports only CrossFire for multiple GPUs.

Put all those pieces together and the choice for GPU on the i7 Entry system is the Radeon 4870 1 GB. The best value today is the MSI R4870-T2D1G, which is just $205 after a $25 rebate. The best value in HD 4870 1GB cards shifts day-by-day, but you can generally shop for the lowest price on a 4870 1GB card and end up with a good quality card.

Triple-channel memory comes in a 3GB kit (3x1GB) or a 6GB kit (3x2GB). Value dictates the 3GB choice with a great memory package from Patriot. The Viper DDR3-1333 comes as a 3GB kit won't break the bank at $70. For just $70 more, you can upgrade to a 6GB DDR3-1333 kit instead.

Good cases and power supplies are either used forever or they go with the old board on a system upgrade. Generally, it's best to invest in the best case and power supply you can afford. Since this is an Entry i7 we can cut costs on the case and PSU, and with numerous price cuts and rebates available on these components you can still get a lot of value for just a little money.

The Cooler Master Centurion 534 is a good value no matter how you look at it. It does come in different configurations, and the RC-534-SKN2-GP case is a good choice since it comes with three 120mm fans (front, side, and back) for cooling and installation requires no tools other than a screwdriver for mounting the motherboard. There are also plenty of drive bay options with five external 5.25" bays, one external 3.5", and four internal 3.5". Front USB/Firewire/Audio connectors are also featured. Builders report smooth edges and no sharp pieces to cut your hand during assembly. Even the expansion slots are screwless in this design. Our selection at $50 is black with a brushed aluminum and mesh front, but the case is also available in all black if you prefer at $55.

The power supply is an excellent value at $70. That $70 buys a 700W OCZ StealthXStream after a $20 rebate. This OCZ PSU specifies an efficiency of greater than 85% with both overload and overvoltage protection. The OCZ StealthXStream 700W should be able to handle whatever you ask of it in powering or overclocking a more basic Core i7 920 system.

Hard drive capacity continues to grow, as you can see in our selection of the Samsung SpinPoint 1TB (1000GB) hard drive at just $95. For less than $100 the value is incredible. While there are differences between hard drives, outside of running benchmarks most people aren't likely to notice the difference in performance between Western Digital, Seagate, Samsung, Hitachi, and other major brands. All are worthy of consideration if the price per gigabyte (or terabyte) is right.

The optical drive for an entry Core i7 system needs to play Blu-ray disks. The flexible LG GGC-H20LK has the ability to read both Blu-ray and HD-DVD format disks. It also can burn DVDs at 16x speed in single or dual-layer formats. It cannot, however, burn 25GB/50GB Blu-ray disks; adding that capability raises the cost to around $200. A BD burner like the LG 6X Blu-ray Burner GGW-H20LK is a good choice if you require a Blu-ray burner.

After reviewing the current state of onboard audio, we concluded that the onboard solutions are plenty adequate for most of today's computer users. That is why we stuck with the onboard audio on the Gigabyte. Speakers are the 5.1 Creative Inspire T6100 76W system. At $70 the T6100 delivers very good 5.1 surround sound for the price.

The LCD display resolution for the Entry Core i7 system is 1080p full HD (1920x1080). The monitor is one of the new class of 21.5" monitors with a resolution the same as last generation's 24" LCD monitors. The newest monitors use a 16:9 "true HD" ratio instead of last generation's 16:10. The resolution is the same as 24" monitors, but the price is a bargain at $190, which saves at least $100. The Acer H213Hbmid monitor is rated at 5ms and features HDMI inputs for easy hookup to the latest video cards like the MSI Radeon 4870 1GB used in this entry Core i7 system.

By paring components to the items that most affected performance, the bottom line price for a complete Core i7 is cut by more than 25% from our choices of just a few weeks ago. This reduces the price of entry for a complete i7 system to $1450 including a 1080p LCD Monitor, keyboard/mouse, 5.1 speakers, Blu-ray player, 1TB drive, Radeon 4870 1GB graphics, and Windows Vista OS. Performance of this i7 Entry system is definitely in the high-end class, although we will be extending that performance even further in our builds of the Core i7 Overclocking System, and Core i7 Dream system.

    I agree, with the right sound card, a good 2.1 would prove a much better investment than an entry level 5.1 surround. But of course, there's also the logitech g51:-) Reply

    I was thinking the same thing about the audio choices. They are all over the map and no options for home theater or gaming in the dream system. On the budget or overclocking system I would much rather have a great sounding 2.0 or 2.1 setup or even headphones than a cheap 5.1 system.

    Of course it totally blows the budget point here but a set of Swans M10/M12 would work on the low end system and blows away just about everything in the under $100 market, D1080MKII for midrange at $125 now and they sound almost as good as the next choice, which is the M200 MKII at the high end ($189) for the more musically inclined. Or something similar to those choices from another decent supplier of audio, even the Klipsch ProMedia 2.1 can be had for around a $100 now or the M-Audio AV30s at $99. A good sound card is needed to get the best out of these speakers but they will even make onboard audio sound better.

    I will not argue too much about the dream speaker setup considering the emphasis is on PC audio that includes games but why not consider the Auzentech X-FI Forte for the sound card then or the X-FI HT HD for both gaming and home theater.

    It just seems as if the audio section was slapped together as an after thought. At least give some alternatives for each setup to mix and match, that holds true for the other stuff as well. List a primary setup in detail like you have and then have a separate box for alternatives. One would have to assume that there is at least two choices in the best of categories listed in the article.

    this is insane. i thought an entry system would have fewer luxuries than this build would. a 1080p screen? a 1 TB drive, who uses that much storage? i have about 30 dvd quality movies, tons of music, and a bunch of modern games installed, some of which have multiple installation folders and i am only using 200 GB at most. the video card is good but is it entry? more like a 9800gt id think. surround sound? a 700 watt power supply powering one card? and an expensive optical drive. i didn't know everyone was a gamer or multimedia enthusiast these days....oh excuse me i used the term lightly, because i didn't mention quad sli or cfx when referring to gamer. some people have budgets, and when they do i doubt they look for an article like this relating to "entry", when you could easily save hundreds of dollars if your just wanting to taste i7.

    With 2TB drives launching soon I never imagined the selection of a $95 1TB hard drive would be called extravagant. By all means refer back to the Under $1000 guide if that better meets your needs and save $30 by choosing a 500GB drive instead.

    I don't see the point of buying a Core i7 if you don't need or won't use the power of the CPU. Saddling even the Entry i7 with a sub-standard graphics system is poor value. If the cheapest 1080p monitor on the market at $190 is too much you can crank down the monitor and select a cheaper video card. Then, why bother with an i7 - buy a cheaper and capable CPU and upgrade your monitor and video to improve overall system performance.

    I confess that I really don't understand why you would buy an house in Beverly Hills, even the cheapest house in Beverly Hills, and fill it with K-Mart knock down furniture.

    Really? You can't imagine someone buying a house in Beverly Hills. It is called house rich, cash poor. But really? Wouldn't the equity you create in a house in Beverly Hills be worth it. I think this is a bad example since houses are investments and people buy too much house all the time. Consider the current times as evidence of this fact. Reply

    On a related note, it's worth noting that CUDA for NVIDIA GPUs and other GPGPU tools (OpenCL, DX11) are really starting to show promise (i.e. Photoshop CS4 uses some GPU acceleration), so at some point you may seriously consider buying a cheaper CPU with a top-end GPU for computational work. That's what Tesla is targeted at, for example. A $200 GPU for a Core i7 makes perfect sense; if you don't need a $200 GPU, I can't imagine why you'd really need eight logical cores. Maybe all you do is 3D rendering or video work... but don't those benefit from a decent GPU as well? Reply

    I was going to state that prior to the release of CS4, I had zero use for 3D capabilities higher than that provided by integrated graphics. If I were going to build a system today, I would aim for under $100 on the video card and see if it actually helped much, if some killer app for GPGPU does actually come out can always upgrade. Reply

    One thing I'd require in a build, is atleast 4gig's of ram. If your forking out 1000+ it should be manditory... Or with the case of i7 6gigs. Reply
  • Spivonious - Thursday, February 05, 2009 - link

    I agree. The "entry" system is more like a "under $2000" system. I bet with some effort you could build a solidly performing i7 system for under $1000. Reply
