verdegallardo :
The 7970 - ok if that's better than 2 560 ti's or one 580, I'll get that one - it's about the same price as the 560 tis anyway. Is this the one you recommend?
It's not .... one 7970 gets 675 fps in the Guru3D test suite, twin 900 Mhz 560 Ti's get 862 ..... that's 187 more fps (28%) for $140 (25%) less money. However if ya not gaming, I'm not really getting the "what's better" part w/o knowing what exactly you are going to ebb doing...... for example if doing vieo editing or 3 rendering for example, I' say get a CUDA capable card... SLI'ing the generally won't aid you in those tasks tho.
Guru3D uses the following games in their test suite, COD-MW, Bad Company 2, Dirt 2, Far Cry 2, Metro 2033, Dawn of Discovery, Crysis Warhead. Total fps (summing fps in each game @ 1920 x 1200) for the various options in parenthesis (single card / SL or CF) are tabulated below along with their cost in dollars per frame single card - CF or SLI:
$ 240.00 6950 Frozr OC (484/759) $ 0.50 - $ 0.63
$ 205.00 560 Ti (455/792) $ 0.45 - $ 0.52
$ 320.00 6970 (526/825) $ 0.61 - $ 0.78
$ 205.00 560 Ti - 900 Mhz (495/862) $ 0.41 - $ 0.48
$ 340.00 570 (524/873) $ 0.65 - $ 0.78
$ 500.00 580 (616/953) $ 0.81 - $ 1.05

Other comments .....
CPU - if you can justify a 2600k over the 2500k for the $100 an 0.1 GHz performance increase, I don't get why ya can't justify the additional 0.1 Ghz from the 2700k for just a $40 increase in cost. I' get the 2500k or the 2700k w/ HT, the 2600k just doesn't have a niche anymore due to the minimal price increase for the 2700k.
SSD - If you expecting any more than bragging rights for benchmark scores from the SSD's in RAID 0, you will be sorely disappointed.
The H series Coolers are quite noisy and frankly the better air coolers outperform all but the H100. If among your MoBo criteria is wide spacing between GFX PCI-E slots (i.e WS Revolution), you will find that the reservoir oft hits the top GFX card when mounted on the rear of the case.

Memory - Make sure low profile if using an air cooler
Case / PSU - The 922 has no front USB 3.0 ports which kills it for me. The Corsair 1050 an 1000, unlike the other members of the HX series, is frankly a rather pedestrian PSU.....getting just an 8.5 rating from jonnyguru (all the others HX series get 10.0's). Unless you go w/ twin 580's, I'd get an 850 watter
Alternatives (all PSU's are 10.0 jonnyguru rated):
HAF-X w/ HX850
Antec 1200 V3 w/ CP-850
Corsair 500R w/ HX850
