I've decided to switch up the RAM to this:
Newegg.com - OCZ Reaper HPC 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory - Desktop Memory
and I've decided to take your advice on the PSU and get this:
Newegg.com - PC Power & Cooling S75QB 750W EPS12V Power Supply 100 - 240 V UL, ULC, CE, CB, RoHS - Power Supplies
I would really like to know what you recommend for cooling the processor though, what are some good cooling solutions?
Also, why would a QX9650 not be better than a Q6600? When I start overclocking won't it make a HUGE difference?
