And how exactly do you fit all that in the budget given?The LK is the cheapest 2xPCI-E 3.0 SLI/CF Asus motherboard, has the best Bios layout and overclocks better than any in this price range. The audio chip ACL892 isn't any good. A soundcard such as the $80 Asus Xonar 7.1 (AV100 audio chip) will improve your gaming experience. If you don't want to add a sound card then the Asrock Extreme4 (ACL898 audio chip) is better for gaming. Bios isn't as refined and overclocks a little less but a solid budget choice.
You should get a better PSU. Seasonic's most affordable Gold 650W, The SSR-650RM is $30 more expensive than your choice but is a great value and your rig will thank you for it. If you might add another video card (because your motherboard can) then 750W would be enough.
Try to fit a CPu cooler in your budget. $30~35, Arctic i3 is my first choice, then CM hyper 212 Evo.
The only RAM I use is the Samsung 30nm. Kingston used to be my favorite but not since these babies came along.
For HDs, WD Blacks are fast, loud, power hungry and expensive, while Greens are slower, efficient, and cheaper. Blue is a mix of both. Your choice should depend on whether you want an SSD or not. I would grab an SSD and go for Green as it is a perfect storage media for all non-application files. If you can manage to play no more than 5 to 6 games a season, and transfer your games to your HD once you're done, then 128GB SSd should be sufficient. If you're buying now then the Samsung 840 (non-pro) is the best bang for $100 bucks. Wait a bit longer and Crucial M5 will be out.
Don't buy the old WD HDs! Websites have the old and new models mixed up all over the place. Make sure the last 4 digits of the model number reads "_NRSN". Those are the new WD HDs.
For your case, don't forget to add two more fans for total of four. you already have 1 front intake so add a side intake fan, and already a rear exhaust so add a top exhaust fan. Other choices that I prefer in that price range are the rosewill R5, or the Antec 300.
Now for your GPU all I can say is sell your kidney and get the Gigabyte HD 7970 3GB. This $400 card used to be $600 8 months ago. Overclocks like a champ and as quite as the best. It's $100 more than the HD 7950 but with Hitman Absolution and Far Cry 3, and Crysis 3 in the future, the %10 increase in performance vs the %25 increase in price is worth it imo.
Good luck with your build and please do read reviews as much as you can for the parts mentioned by me and others. We're not taking any risks as you are.
Really?....according to what?AMD's new Tahiti LE 7870 is a wolf in sheep's clothing. It smokes the 7950 by a quite substantial margin. Could only find one on newegg, for about $30 less than a 660Ti. Not sure how it compares to a 660Ti, though.
make sure to go to memory express and order from there, they will price beat it by 25 percent of the difference and they have a flat shipping rate, which is pretty solid!
