Mushkin Enhanced Redline 3x2 GB 1600 mhz CAS Latency 6 for the same price
Sticks mentioned above or Corsair XMS3 3x2 GB 1600 mhz CAS Latency 7
for $180. Dominators are a waste of money.
Mobo: Asus P6X58D Premium $310. Pay a little more for the USB 3/SATA III on a hgiher quality board.
PSU: SeaSonic 850W $110. Higher quality, more efficient.
Cooling: Coolermaster Hyper 212 $30. Better and cheaper.
You don't need an anti static wristband.
That should be about the same price, but better performance
For gaming, the i5-750 is just as good, and a build would be $280 cheaper, enough that you could get a SSD as a boot/app drive. What I would change (besides the above) for an i5 build:
CPU: i5-750 $200
Mobo: Asus P7P55D-E Pro $190
RAM: Corsair XMS3 2x2 GB 1600 mhz CAS Latency 7 $110
HDD: Samsung Spinpoint F3 1 TB $90 (assuming you wanted to do RAID 0 with the 2x 500 GB for booting)
Same price as above.
