AMD Mainstream PC

To be completely honest, the AMD Phenom II X3 720 Black Edition is not quite the equal of Intel's Core i3-530. In our tests, it came in slightly behind in practically every single benchmark, regardless of how many threads the applications used. But it comes very close, and if you buy into the value-packed AM3 platform using the X3 720 as your entry point, you'll have plenty of other features to go along with it.

Besides, when you judge it on its own merits, the $125 2.8GHz Phenom II X3 720 Heka Black Edition is still a very promising processor. Like the Athlon II X3 435 Rana we recommended for our entry-level box, the 720 Heka is at the sweet spot between dual- and quad-cores in AMD's lineup, performing better than Athlon II X4s in benchmarks that favor fewer threads and better than Phenom II X2s in benchmarks that favor more. It's a powerful overclocker, capable of a stable 3.8GHz on air and up to 3.3GHz on stock voltage, and the Black Edition suffix means you'll have an unlocked multiplier to help you get there. And of course, as with any AMD tri-core, you have a chance of unlocking its hidden fourth core with ACC. If you don't see yourself doing a lot of multitasking or multithreaded work, you could easily shave $34 by going with the $91 Phenom II X2 550 BE instead; if you plan on doing 3D rendering and video editing all day, you'd can save $23 by purchasing the $102 Athlon II X4 630 Propus. But if you're not certain where your CPU might take you and you want to maximize the possibilities, the 720 Heka is the right chip at the right price.

And to house that chip, we've got not one but two bang-for-the-buck motherboard possibilities from Gigabyte. If you're not planning to buy a discrete GPU to power video and gaming, we recommend the GA-MA790GPT-UD3H, a full-sized ATX motherboard built around the 790GX / SB750 chipset. At the excellent price of only $90 after rebate ($105 without) the MA790GPT-UD3H features an onboard Radeon HD 3300 IGP with 128MB of DDR3 sideport memory, which beats both AMD's newer 785G and the Intel Core i3-530's Intel HD Graphics in terms of raw power. It also comes with Realtek's premium ALC889A 7.1 channel HD audio chipset and loads of opportunities for expansion.

The SB750 Southbridge provides the standard four flavors of RAID (0/1/5/10) across six SATA 3GB/s ports, four facing front; connectivity includes VGA, DVI and HDMI video-out, six USB 2.0, one 1394a, a combo PS/2, Realtek 8111C GbE, six audio ports and a separate S/PDIF optical out on the rear panel; and the board supports all current Athlon II and Phenom II processors along with 16GB of DDR3-1666 memory in four banks. The board's layout leaves something to be desired, with one of three fan headers and its three USB 2.0 headers sandwiched haphazardly amongst the PCIe slots, but it does include a pair of PCIe x16 slots (with 8 lanes for each in CrossFire), three PCIe x1 and a pair of PCI slots, in addition to an IDE header, two 1394a headers and a legacy floppy connector.

However, if you do plan to buy a discrete GPU, we'd recommend the Gigabyte GA-MA790XT-UD4P instead. For the same $90 after rebate, it loses the onboard video of the 790GX series but gains the newer Realtek 8111DL NIC for Gigabit Ethernet, one 1394b port and one coaxial S/PDIF port on the rear panel. It has a more sensible layout and a reputation for moderate overclocking that should serve you well if you decide to push that tri-core CPU to its full potential.

As with our Mainstream Intel PC, onboard graphics make even a $100 discrete video card optional, but it's somewhat more of a talking point when that 790GX graphics still doesn't allow bitstreaming of Dolby TrueHD and DTS-HD or 8-channel LPCM audio output over HDMI. Though the Radeon 4850 is our go-to budget gaming choice at $100, if you're looking for this AMD PC to pull double duty as a home theater box, you might want to consider a Radeon 5000 series card like the $100 Radeon HD 5670 instead.

    Unless you are building a HTPC or something else where form-factor is important, wouldn't a standard ATX mobo be a better option. Quite apart from the very useful additional PCI and PCIe sockets the ATX board will have which will allow the PC to be used for practically anything, there is generally room for more of other assorted headers like SATA and USB for adding further drivers and whatnot internally as well (and any decent ATX mid-tower will have plenty of 3.5" and 5.25" bays for them all).

    Admittedly I haven't checked prices for several years (mid 2005 when I built my current box, actually), ATX mobos were only a bit more expensive than uATX back then and I assume the same is true today. Even if you don't use most of the extra features, those you end up using at some point easily (for me) justify the small additional cost.

    It was recently brought to my attention that there is a really good Samsung HD that is the same size, same price and double the performance! In many cases it actually out performs the Raptors (which i have...)

    Samsung HD502HJ

    I would post a link to the benchmarks but I'm not really sure if that's Kosher or not!?
  • SeanHollister - Friday, February 12, 2010 - link

    As I mention to another commenter above, we were actually originally going to go for the Samsung HD502HJ, but not for the reason you suggest. Though benchmarks do show the Samsung having higher sequential read and write speeds than some contemporaries, it seems to suffer somewhat in access times and IOPS such that it's not much better (though certainly not worse) in real-world applications than the WD we chose.

    That doesn't keep me from wanting to test one for myself, though :-)

    It's good to see some mention of a budget SSD (Intel X25-V), though it could really use the coverage and analysis of a full article. It's frustrating that this site only seems to cover the fastest and biggest SSDs that would almost double the cost of a reasonably configured system. What I'd like to see is a full comparison of the lower capacity drives in the 30-40GB range from the persepective of using it as a boot / application drive while storing user data on a traditional disk. This is what I'll be looking for in the next few months, but so far I haven't seen much information that would help guide my purchase.

    I too, was also glad to see a mention of an SSD in the upgrades section. The time has arrived.

    Anand did cover the Kingston 40GB SSD in a recent SSD article (which is the same thing as the Intel 40GB....same hardware, same controller, and now that you can flash the Intel firmware onto the Kingston....same firmware WITH TRIM). It compares very favorably to the bigger SSDs on random reads.

    On pg 3 in the last paragraph you refer to the RAM as Corsair but the recommendation is G Skill.

    Good read, the options are many and while one can always find other viable options it's nice to have things narrowed down sometimes.
  • SeanHollister - Friday, February 12, 2010 - link

    Thanks for catching that. We originally chose Corsair RAM, but they bumped the price of their modules $5 at the last minute.

    I really wish this site would take a look at samsung hard drives, they are really cheap and the new f3 line is great. the samsung f3 1tb(which i now own :P) is one of, if not THE fastest 1tb hard drive, and is silent. i run my computer with no side panel on my desk, and i cannot hear it apart from initial spin up. It absolutely destroys my 320gb Seagate from a year and a half ago(:duh:). i think 1tb is the absolute lowest any builder should go today, you spend $20-30 more for twice as much size and better performance. I had a 160gb seagate for 5 years, and never thought I'd need more, then i got a 320gb and filled it in less then a year, my new 1tb is now half full(my 320 is pulling backup duty now), YOU CAN NEVER HAVE TOO MUCH!
  • SeanHollister - Friday, February 12, 2010 - link

    Funny you should mention that: we were originally going to go with a Samsung F3 500GB HD502HJ, but the retailers with the best price ran out of stock the day before the article went live.

    While it's true that newer hard drives are faster and quieter no matter the manufacturer, when you're comparing ones from the same generation at the same price point, it's hard to see a difference in real-life performance -- at least one big enough to justify spending extra on. :-)
  • Spivonious - Friday, February 12, 2010 - link

    I'm curious why the E5300 was chosen, when the E3200 is just as capable and cheaper. I've been using it in my HTPC for 6 months and have yet to run into any slowness. It makes perfect sense in my mind for an entry-level non-gaming system.
