Im sure that system will work well. Looks like you have chosed some good quality components.
5. Take a look at the PNY GTX580 card as an alternative to the 6970. This has a closed loop water cooling system on it, and has had some great reviews. There are two versions of the card. One version cools your cpu and your video card on a single system.
6. Personally i would spend a little bit extra and go for a 120 GB corsair ssd drive. Very little cost difference for 25% more capacity.
7. Check the compatibility chart from your mobo manufacturer for the ram chips. That way you will be getting the most compatible chips and save yourself an lot of time and effort.
11. You wont need a cpu cooler if you have a PNY water cooled graphics card (with cpu cap)
