To keep the crossfire option open with the 4870 you should go with the 750w Corsair. This site has reviews of all 3 of those cases, read up maybe they'll find something you've missed and make your call easier. http://www.hardwaresecrets.com/page/case/15/2
At your resolution i'd rather get the single best GPU solution i could squeeze in hehe. In fact this is doable in Full HD gaming as well no problems ^^ Cheaper with 720BE i guess but a config with a quad in Doable with a HD4890 too
Probably HD 4850, HD 4870, maybe a lower model. My concern is the heat issue of the 4850 and 4870. I've read some models have a non stock cooler and/or heat exhaust to combat that. It's confusing which one to choose with all the variations available.
I was thinking 4GB (2 x 2GB) DDR3 1333 (PC3 10666). This is the component that I find most confusing. Still researching.
PSU: Since the mobo can only do one GPU, the Corsair 650w is more than enough and will serve you for several builds. $80 amir
Case: All 4 are way better than good enough. Pick the one you like the styling the best. The storm scout has free shipping which makes it my pick. That and I think it looks cooler than the rest. If you like one of the others better, check ZZF for it, they have free shipping on a lot of stuff right now.
HDD: Great choice
All that adds up to $560 ($90 case) leaving $140-190 for upgrades and the CPU. If you want to come in under budget for $680, the 720x3 is a solid CPU and will serve you well. If you want to be within your budget, the 945 puts the total at $730 or if you get the CPU from ZZF, the 955be is $200 putting you right at the $750. You will be able to game like a mad man with the 4870 at that res already and the x3 is still a little more CPU than most games can use. So if you want to have some free cash, get the x3, if you want to go CPU crazy, the either x4.
So I think I'm going to hold off on purchasing my system until late August/early September to see if pricing lowers. I'm curious to see the pricing structure after the X4 965 BE is released.
I'm going to buy a couple of the components now, namely the PSU and HDD, since I can get a MIR and free shipping.
I'm indecisive about the PSU. Should I get the CORSAIR CMPSU-650TX 650W or CORSAIR CMPSU-750TX 750W, considering I plan to overclock and possibly add a better video card down the line or possibly CrossFire.
I would salvage the NEC DVD burner, the DVD rom drive isnt very useful anymore. Are they both IDE? If so be aware that IDE cables arent very long these days, my DVD drive has to be in the lowest 5.25" slot on my Antec 300 because the IDE cable isnt long enough.
