The why's .....

MoBo - WS revolution has NF200 (Gigabyte doesn't) ... allows x16 x16 in SLI. Giga to the best of my knowledge only does x8 x8 which would be a significant bottleneck on the 590 BTW

RAM - I have not seen anything published as yet showing me of any significant improvement above DDR3-1600 on Sandy Bridge. For the price, I'd rather have CAS 6 or 7 DDR3-1600

GFX - Guru3D had a broad database of GFX card tests in which they use the following games COD-MW, Bad Company 2, Dirt 2, Far Cry 2, Metro 2033, Dawn of Discovery, Crysis Warhead.

At 700, a GTX 590 will get you a total fps of 881 in the above games. Twin 560 Ti (900 MHz versions) will get you just 19 fps less at 862 for $430

So, before ya think it, you're gonna say that you can always add another 590 ... and ya can but to what end. Adding a 2nd 590 scales only another 14.6 % and $700 is a lot pf moola to pay for that piddling improvement to 982 fps. If ya now thinking 6990, that card scored 762 fps in the same text, only 903 in CF.

Looking at alternatives to the 560's, and based upon total fps in the same game set, ya have the following choices (single card / SL or CF).

6950 (479/751)
560 Ti (455/792)
6970 (526/825)
560 Ti - 900 Mhz (495/862)
570 (524/873)
580 (616/953)
6990 (762/903)
590 (881/982)

Cooler - This isn't my 1st choice .... fr max performance I woulda went with the Prolimatech Genesis or the Thermalright Silver Arrow. But user wanted to be able to add RAM at a later date w/o messing w/ cooler and the Kuler was only off the "record holder" by 2.9C. Here's two recent test results (test uses single hi speed fan for all tests to take the fans used outta the equation:

Test 1
Corsair H50 68.1
Coolit Vantage A.L.C.
Corsair H70 64.7
Coolit ECO A.L.C. 64.3
Cooler Master V6 GT 59.5
Prolimatech Super Mega 59.4
Antec Kühler H2O 620 58.7
Thermalright Venomous X 58.0
Thermalright Silver Arrow 55.8

Test 2
Prolimatech Megahalems 56.1
Thermalright Venemous X 56.8
CoolIT ECO A.L.C. 58.9
Scythe Mugen 2 60.8
Thermaltake Frio 62.7
Titan Fenrir 65.6
Xigmatek Thor's Hammer 66.3
Corsair H50 67.4

Note ya can't compare results from test 1 w/ test 2 as different system used.

TIM - It has the best numbers and no curing time issues.

SSD - 64 GB is a but small for "convenient" usage. I have built many Win 7 systems for people with 64 GB. C:\ drives ..... About evcery 6 months I get a call asking for help "cleaning them out". The V100 is less than half the speed of the Vertex 3

HD - 7200.10 is 2 generations old and therefore very slow by today's standards. If ya willing to spend some extra $, the Seagate XT is faster than the normal "big 3 picks" (WD Black, Spinpoint F3, Seagate 7200.12). Most of this is due to increased areal density. The SATA III interface only has a minor impact on overall seed as transfers from cache will benefit from the 6 GB/s interface but the mechanical drive doesn't come anywhere near exceeding th SATA II bandwidth.

Case / PSU - Nice touvh on that case, adding a BlacX HD docking station to the build.....at $89 on newegg it's an attractive price to0. I have never built with the case tho so I hesitate to say anything else. The PSU however is not a direction I'd go. You have not sized it to handle twin 590's. One 590 or twin factory OC'd 560's will require a very good 750 watter or greater. Since ya can't use the CP-850 as it's CPX form factor makes it incompatible w/ your case, I'd suggest the XFX Black Edition 750 or 850 watters. The Black's get the same 10.0 performance rating as the Corsair HX and AX series, Antec CD and SG series and Seasonic X series .... however the Black's are much less expensive generally than their aforementioned equals.
