so guys i have a question for you, should i build my computer or should i buy a pre built. my budget is a little less than a thousand dollars USD. i want to be able to run any game at 60+ fps on ultra high settings. (skyrim,bf3,starcraft 2,etc) what is the best video card to get? and what are the best peices to get? i'm not tech savvy but i do believe with 1000$ i can make a machine that can do this.
Mobo: Asrock p67 Extreme 3 gen.3
Ram: whatever cheap 8gb 1600mhz kit you can find, look to g.skill
Case: Haf 912
CPU Cooler: CM Hyper 212
HDD: western digital caviar blue 500gb
SSD: can't afford and not important on this budget compared to other component budget
PSU: cheapest Seasonic/Corsair/Enermax/Antec 600W+ single 12v rail you can find, probably will be 80 dollar ballpark at minimum
GPU: AMD 7950 (xfx, sapphire, gigabyte, asus whoever you can find cheapest)
Will run you in the 1000-1050 range. That's what I would recommend in your ballpark.
re-use current keyboard/mouse/monitor for the time being.
For the record, this build will max ALMOST everything out there, aside from the most ridiculous, poorly coded benchmark style games such as Crysis on full max settings w/ custom mods, and even then might come damn close to maxing it, up to 1920x1200.
Use my recommendation. Without going into elaborate details, the graphics card is several tiers more powerful in my list and you're spending budget in places (caviar black) that aren't as important as others for maxing games (gpu). Everything else is fine though but I really recommend only the brands of PSU that I listed specifically.
Best of luck to ya bud. And don't worry too much about building things like fans into your initial budget. You can always add them a paycheck down the road, and the Haf 912 already gets great airflow from just a couple of fans, for being such a cheap case. You save a few bucks going with the p67 chipset as opposed to z68 and you won't be using intel onboard graphics, nor are you using an SSD in this initial build and the gains from both z68 optimization features aren't worth the sacrificed budget toward important components. Just my 2 cents.
Aside from the minutiae of details, if you get an 8gb kit of DDR3 1600mhz cl9 ram rated at 1.5 or lower volts (this is the max recommended for i5-2500k systems), then ram is ram. It'll run you in the 40 dollar range presently. G.skill, Corsair, Kingston, Mushkin, etc all fine sources.
