I don't see you benefitting from Z68

For an extra $20, ya can grab the WS Revolution which is something I'd do w/ anything higher than 6950 in CF or 560 Ti in SLI

While the NF200 doesn’t completely solve the dearth of PCIe lanes available on LGA 1155 platforms, its ability to send identical data to multiple cards makes it perfect for SLI and CrossFire. That benefit, when combined with the Sandy Bridge processor’s superior performance and overclocking capabilities, slams the lid on the coffin for X58 gaming. Anyone who needs the added flexibility of X58 to host other devices, such as high-end drive controllers or six-core processors in a workstation environment, must bow to the gaming superiority of NF200-equiped Sandy Bridge motherboards like Asus' P8P67 WS Revolution.
The 590 and 6990 are far from being worth their costs
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:
$ 360.00 6970 (526/825) $ 0.68 - $ 0.87
$ 220.00 560 Ti - 900 Mhz (495/862) $ 0.44 - $ 0.51
$ 320.00 570 (524/873) $ 0.61 - $ 0.73
$ 480.00 580 (616/953) $ 0.78 - $ 1.01
$ 725.00 6990 (762/903) $ 0.95 - $ 1.61
$ 750.00 590 (881/982) $ 0.79 - $ 1.43
$725 for 762 fps ???? The 900 MHz 560 gives you 100 fps more for about $440.
I'd do the onboard sound and only add the Xonar later if you feel OB comes up short......most don't
I'd drop to 2 x 4GB as 16GB shows no advantage in gaming. More importantly drop the silly heat sinks and get Corsair's new short version

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.
If gaming, I'd get the 2500k as the 2600k's HT isn't going to do squat for ya.
Why the ole tech Bigfoot ? I's suggest a modern 550 MBps SSD ,ike the Vertex 3 or Corsair Force Series 3
Ya went high end on everything and then went cheap on the Case, PSU and cooler.
Best quiet cooler to my mind is Thermalright Silver Arrow (check out the Hyper 612 also if it ever hits the shelves). V6 GT is nice performer thermally but loud as hell.

My fav case / PSU combo is the CP_850 w/ either the Antec 1200V3, DF-85 or P183/P193. Jonnyguru writes that you'd have to spend twice as much for a comparable performing PSU and he gives it a 10.0 performance rating. SilentPCreview.com writes:

he Antec CP-850 is a superlative power supply by almost any standard. Its electrical performance is up at the level of its more expensive brethren, the Signature 650 and 850, and Seasonic's flagship, the M12D-850: Voltage regulation is extremely tight for all the lines at all loads, and the ripple noise is amazingly low.......
The noise performance is excellent, with the <400W performance matching or bettering virtually every PSU tested thus far. Above 500W load in our heat box, the noise level goes over 40 dBA@1m, or about the norm for PSUs rated this high. It has the virtue keeping itself extremely cool, however, cooler than any other PSU we've tested at such high loads.
A serious consideration is that in each of the three compatible Antec cases, the CP-850 mounts on the bottom, and the intake for the PSU is quite separate from the rest of the system. In the P193 and P183, the PSU is in an entirely separate thermal chamber, and in the model 1200, a direct path can be maintained to the directly opposite, wide-open front vent. This means that our extreme hot box test conditions never apply to the CP-850; in other words, SPCR's test environment is unrealistically hot for the CP-850. Our atypical spot check with a room ambient thermal test showed the CP-850 would reach only 24 dBA@1m at 700W load in a 27°C working environment. This is ridiculously quiet for such high power output.
The above is an obviously unfair advantage for the CP-850... but what of it? Antec has used an integrated systems approach for its CP-850 and its best cases, and if that approach is an advantage over all other case/PSU combinations, then, all the more power to Antec!......
For the quiet-seeking computer gaming enthusiast, the CP-850 (along with any of the three [four now w/ the DF-85] compatible cases) is something of a godsend. Fantastically stable power, super low noise at any power load, long expected reliability due to excellent cooling, modular cabling, and all at a price that's no higher than many high end 6~700W models.
Next up, I'd opt for the HAF-X w/ the AX850 (or something bigger if warranted).
