Congrats.
I'm waiting on some parts for my new build as well. I missed the fever of looking for new hardware.
I kept my q6600@2.4/GTX285/4gbDDR2 to see how it will run. It runs but i have to sacrifice too much beauty to run on it.
The old box is 3.5 years old anyway, it served me good, but is a good time to let it go.
My system will be quite similar with yours. I already have the EVGA GTX590, I'm waiting on the i7 2600k, Asus ASUS P8Z68-V Pro, crucial M4 256GB SSD and 2x4GB of Corsair DDR3.
I should have all the parts sometimes next week and looking forward to put it all together.
