Core i7 System Buyers Guide

by Wesley Fink on February 5, 2009 3:00 AM EST

Final Words

The Intel Core i7 processor currently owns the high end of the market, which is the reason the CPU prices remain high relative to Intel Core 2 Quad and the AMD Phenom II. The cheapest Core i7 920 CPU is around $300, with two more models going for $600 and $1000. In addition, the Core i7 uses a new socket 1366 and supports the first triple-channel DDR3 memory configuration. That means new Core i7 buyers will be shopping for a number of new and unique components as they move to Core i7.

Despite the high cost of the CPU and the uniqueness of some components, we have shown that it is possible to build a complete high performance Core i7 system for as little as $1450. That price is for a system with 1TB hard drive, Blu-ray player/DVD burner, a Radeon HD 4870 1GB video card, 1920x1080 monitor, keyboard/mouse, and even Windows Vista Home Premium. If you have some components that are compatible with a Core i7 build, you can reduce the cost even further. Just be sure you will not be leaving performance behind with the components you are considering moving over to a new Core i7 build.

We also showed an extremely flexible Core i7 overclocking system build with components selected to support overclocks to 4.0GHz with the Core i7 920 processor. While the cost was just a bit over $2000 for the complete system, the overclocking i7 system should carry you considerably higher than the current top-line Core i7 965 which runs at 3.2GHz. The OC system was pushed toward value overclocking but the $1010 965 CPU is unlocked and it could be the basis of a "highest performance at any cost" Core i7 overclocking system.

Finally, our Core i7 Dream system used all the best performing parts we could assemble in a $5000 "performance king" system built around a 30" S-IPS panel LCD driven by an NVIDIA GTX 295 dual GPU video card. The Dream Core i7 includes the superb Silverstone "positive pressure" aluminum case and the similarly excellent Corsair 1000HX modular power supply driving a $1010 Core i7 965 and 6GB of fast Mushkin DDR3-1600 triple channel memory. We could have carried the "dream" even further with items like RAID 5 storage, a boot SSD RAID, quad SLI with two GTX 295, or a GTX 285 triple SLI setup - supported by the ASUS motherboard used in the dream system. We went as far as $5000 would take us and paused, but there could definitely be more.

The point of all this is that while the Core i7 CPU is the most expensive processor family in today's CPU market, there are still many options. You can build a complete i7 system for less than $1500, use the Core i7 as the heart of an overclocking computer for around $2000 that has incredible performance potential, or use the top $1000 Core i7 965 as the basis for a luxury system with extreme performance for gaming, photo editing, or graphics. The Core i7 is that flexible and is at home in a wide variety of computer configurations. Of course, if all you do is surf the Internet, write email, and work in Microsoft Office, you should save your money and get a more reasonable system - there are plenty of people that simply have no need for eight logical processing cores.

We hope these three systems with widely different goals and prices have given some ideas of where you might like to take a Core i7 build. Wherever you take it, you will be extremely pleased with the Core i7 performance. Core i7 owns the top of the current CPU market because it delivers the best performance in the market today. There is definitely a price premium but you get the best performance you can buy in today's desktop market with an Intel Core i7 system.

    Only 6GB RAM for the dream system surprised me. IIRC, there are benchmarks showing >10% performance improvement for some games when you went from 6GB to 12GB. Similarly, I have Linux benchmarks showing >15% improvement for large-RAM Opteron systems.

    FWIW

    ...as in "nightmare", I guess.
    If you buy that, you can hear your money burning as a background noise...
    The entry level one, on the other hand, is interesting.
    But you should clarify who in the world really would benefit from that kind of thing...

    Benefiting is all subject. Most people think the benefit of choosing real high end compenents is not worth while. But for those with too much cash, why not get what you want?

    I personally wouldn't spend that much, but I'm not going to knock the people that do. It's no different than the people that spend hundreds of thousands extra on peformance between say a Ferrari, and a corvette.

    It's all personal preferences.

    Would it be possible to list the price of all "in the tower" components and sum their cost before adding monitor/speakers/etc? On the concept of selling off a complete C2D tower and replacing it with an i7 tower?

    I would have liked to see a less gaming, more workstation oriented choice. For example, for photoshop a 4870 isn't needed, but more RAM is. Is a 3+ GHz overclock on a 920 possible with 6GB and 12GB RAM configurations? And if so, how good a RAM kit and motherboard are needed?

    I agree with the previous poster that a Blu-Ray drive isn't necessary on the i7 entry system; each user will know if they need Blu-Ray and budget accordingly. Personally I don't plan on jumping on the Blu-Ray train until the burners can be had for under $100.

    Will there be a power consumption guide for i7 coming? All your power supply recommendations are 700W and up, but in the Gigabyte GA-EP45-UD3P test, your published power draw at load for the 920 system is 264W at the wall (which I'm guessing is for a 6GB/single 4870 1GB configuration). Would be nice to know what kind of power is actually drawn when overclocking and such.

    Good job on the entry system. For the dream system, whats with the Evolution X58 mobo. I would much rather have an Asus Rampage X58 or MSI Eclipse X58 mobo.
  • Anonymous Freak - Thursday, February 5, 2009 - link

    Uh... Dare I ask why this Core i7 build guide has pictures of a boxed Core 2 Quad, and a picture of a Socket 775 motherboard on the 'entry' system? (Shouldn't it use the same Core i7 boxed pic as the 'thumbnail' for the article uses; and shouldn't the motherboard picture be a picture of the motherboard the build uses?

    In addition, for the 'Dream' system, there should be a picture of the Core i7 965 Extreme box, not a non-extreme box.

    You have great eyes. The links and images have been corrected. Thanks for helping us out.

    Why thank you! (Blushes and bats eyebrows coyly.)

    Quote: "This Core i7 Overclocking System leans toward the value side of the overclocking equation. Generally parts were selected, like the Core i7 920, because they are a good value that becomes an outstanding value when overclocked."

    I'm confused by this. A Value based overclocker would spend $50 more on a case than the entry case just because he's overclocking? And would buy a Blu-Ray instead of a DVD player?

    I think the sections are fundamentally flawed. A 'value based overclocking option' should be a minor part selection difference on top of function based categories.

    There should be major categories like:
    - Entry
    - Video Encode / Decode
    - Mild Gamer
    - Hardcore Gamer

    Then there should be two or three components for an overclock recommend on each of those sections. You don't need a better case to overclock. You will want a better HSF, might need better memory and in rare cases a PSU upgrade is warranted, but you do not need a Blu-Ray instead of a DVD player or a 3" larger monitor in order to overclock.

    Actually a better case will help your overclock. An aluminum case will disipate heat much better than a metal/plastic case.
