System Builder Marathon: $1,250 Mid-Range PC

Motherboard, Cooler, And Memory

Motherboard: GIGABYTE GA-EX58-DS4

Using the Core i7 CPU means using an Intel X58 chipset, and there are a lot of intriguing X58 motherboards out there already. We chose the Gigabyte GA-EX58-DS4 because of the attractive price and myriad overclocking settings.

The DS4 is the cheapest of Gigabyte's X58 motherboard lineup (Ed.: as of Don's writing--Gigabyte now sells an even cheaper model on NewEgg that you could also consider), so what do we give up for the price? The killer feature is SLI support, as the DS4 only supports up to 3-way CrossFire. For 3-way SLI and CrossFire support, you need to spend $55 more on the EX58-UD5. Other than that, the DS3 and UD5 are extremely close in functionality, with the same BIOS options. The only other notable differences are that the UD5 carries a higher-quality ALC889A HD audio chipset, dual Gigabit LAN connectivity, and more copper on the PCB. Compared to the DS4's ALC888 audio chipset and single Gigabit LAN capability, these are nice features but not deal-breakers for the frugal buyer.

This makes the DS3 a very attractive option as a full-featured Core i7 motherboard at a low price, as long as you don't require SLI support. Since we'll be using a single Radeon 4850 X2 for this month's build, the lack of SLI capability on the DS4 isn't an issue for us.

Memory: 3x1 GB of Crucial DDR3-8500 Triple-Channel Kit CT3KIT12864BA1067

Read Customer Reviews of Crucial's DDR3-8500 Triple-Channel Kit

Crucial’s kit will allow us to run the X58 motherboard’s memory in all of its triple-channel glory. And why go with more than 3 GB of RAM when that’s all Vista 32-bit can see anyway?

At $79, this kit is both cost effective and boasts a CAS latency of 7, which is pretty decent for cheap DDR3. When all factors are considered, this is a perfect choice for our build, and at a great price, too.

    Personally I'd get a cheaper processor and motherboard and go with a Gforce 280 video card. You can get a $180 processor and a $145 motherboard and the 280 card has PhysX built in which is really nice.

    I will hope to see how a high-clocked q9550/q9650 E0 will compare with a i7 920. The Motherboard and RAM will be cheaper. So, you can also get more RAM and faster RAM with the q9550 than the i7 920 with the same cash. Or the high-bandwidth/ lower total memory DDR3 tri-channel might actually do better?
    I don't think a i7 920 /w 3 gigs RAM will work as quickly as a q9550 @ 4.0Ghz with a 470mhz fsb and 4+ gigs RAM -even with quad-core supported apps.
    Anyway, I think the outcome will be hard to predict.

    I think the Q9550/i7 920 comparison would be very informative. I have been considering purchasing a Q9950 in the near future. Let's see it happen.

    I agree with I'd agree with trying to run a comparison with the Q9550. Throwing in an nvidia card would also prove interesting.

    Very good article. I just want to say that the Crucial 3GB triple-channel DDR3 1066 kit costs only $73.99; its price surprised me. Go Crucial! I'm definitely looking into a Crucial memory kit for my next upgrade or build, which might or might not be Core i7, depending how the price wars progress between nVidia and ATI (saying AMD still feels wierd to me when referring to video cards). I noticed how the budget had to "settle" for a 4850 X2 when they Core 2 Duo build had money for a 4870 X2. Hopefully, prices will go down faster, and soon.

    Page 2 - E8500 has 6MB L2 cache, not 4MB.
  • Yes, please try the next system with the Q9550! I would love to see how this processor compares again the new kid on the block. Of course this is the processor I have and also want to see what you get out of it. It would be nice if you chose another Gigabyte board as well to get a more apples to apples comparison with this month's build.
  • Huttfuzz
    Yes we want to see Q9550 against Core i7 920. Both overclocked at the same speed. Let's say 3.8 or something like that.

    Good article, well done. At first I was a bit worried for the Core i7 was going to get humiliated against the higher clocked E8500 but you summary shows just how much progress has been made with developing software that can take advantage of multiple cores.

    The Supreme Commander: Forged Alliance benchmark was surprising out of all the games you tested I expected that game to be the one which showed off what quad cores can do for games. Perhaps you could add in GTA IV into your future benchmarks as that games seems to love quad cores?

    The temps were a little worrying but the Intel Stock cooler isn’t designed with overclocking in mind and you can pretty much guarantee a decent 3rd party cooler will slash those temps by a third.

    One last thing it might be an idea to compare your very first mid range build to your current mid range build, it would give the readers an idea as to how much more bang for buck we get now days.

    well 4850x2 there is only two in newegg 2gb and 1gb which not sure if ATI rly supported as far as drivers compared to its bigger brother
