I'd move up to a tier 3 SSD .... Agility 3 120 GB is Tier 8, according to the chart / article below is a 61% speed difference. The Tier 3 units include the Wildfire which is $165 or $30 more than the unit you selected....not a bad investment for a 61% speed increase.
I'd confirm that the GFX card has a 7 phase VRM ..... most of the ones from EVGA I have looked at in the past have only had the "reference" VRM which IIRC is only 4 phases. Asus and Gigabyte use 7 phase designs, MSI uses 6. EVGA and the reviewers say they use 4....even for the superclocked ones

Skip the tall toothy heat sinks. The only cooling effect of these big coolers is that they "look cool". While they served a purpose (when they were effective) w/ DDR2, they are absolutely useless on DDR3.

At more than 2" tall in certain areas the Corsair Vengeance could pose a problem for users like me who use large coolers such as the Scythe Mugen 2. I was able to use the Corsair Vengeance only after I mounted the fan on my cooler on the backside. Size is definitely a concern with heat spreaders of this size and therefore I encourage users to check that they will have enough space under their heatsinks before purchasing the Corsair Vengeance kit.

The problem I have with the Corsair Vengeance is the same I have with many kits of RAM on the market. Companies insist on putting large coolers on their RAM and it limits the choice in CPU heatsinks that can be used within users system. DDR3 does not require these elaborate coolers with its lower voltages which translate to lower temperatures then RAM saw during the DDR, and DDR2 era. Corsair is correcting this with low profile versions of its Vengeance line but ultimately I would like to see the average size of coolers drop instead of having to look for specific low profile versions of a memory line.
Same memory w/o the useless heat sinks is

If it's a gaming box, ya might wanna save $90 or so and get the 2500k. The premium ya pay for the 2600k is due to its hyperthreading feature.....which is not utilized in games. Video Editing, CAD , rendering and the like do benefit from HT and if that's part of your puting life, if ya can justify getting the 2600k, ya can certainly justify the 2700k.
A 750 watter is fine for reference cards but I'd recommend the 850 watt size if Overclocking the two GPU's and the CPU.
Best are the Antec SG-850, Antec CP-850, Seasonic X 850, Corsair HX850 ...... a step down would be the Corsair TX850 and the XFX Core Edition 850 .... the Core Editions have historically been ridiculously inexpensive but that's starting to change in the last two weeks.
There is no single GPU card that is puts out more than two factory OC'd 560 Ti's
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
$ 320.00 6970 (526/825) $ 0.61 - $ 0.78
$ 215.00 560 Ti - 900 Mhz (495/862) $ 0.43 - $ 0.50
$ 340.00 570 (524/873) $ 0.65 - $ 0.78
$ 500.00 580 (616/953) $ 0.81 - $ 1.05
$ 725.00 6990 (762/903) $ 0.95 - $ 1.61
$ 750.00 590 (881/982) $ 0.85 - $ 1.53
The 590 beats the twin 560's 881 to 862 but it's a twin GPU card and it costs 74% more ($320 extra) for just a 2% performance increase. Even the 7970, which I haven't added to the table yet because of CF issues (COD-MW has negative scaling and Dirt 2 won't run in CF) gets just 675 fps which is 78% of the performance of those 560's for 128% of the price.
There is the "but I can upgrade those cards later" argument.....but adding a 2nd 580 for example gets you just
10% more performance than the twin 560's at 232% of the price. If AMD gets the driver issues sorted out for the 7970 and we start to see scaling in the neighborhood of say the 6970 (162%) ... then that 675 would turn into 1,093 fps or 27% more than the twin 900Mhz 560 Ti's. Two 7970's for $1,100 is easier to justify than two 560's for $430 for the enthusiast .... but still, that's $1.01 per frame for the 7970's (comparable to the 580's $1.05) as compared to $0.50 per frame for the factory OC'd 560's.
