I'm just in the process of building one, but funds have run dry. I purchased a new CPU, RAM, and Mobo. My last machine was good but I blew it up oc-ing too much

CPU, C2D E6600, I've heard a lot of good things and that it is pretty good for OC.

RAM, OCZ PC2-6400 2GB DDR2 Gold XTC, yet again pretty good plus they look good.

MOBO, Gigabyte GA-P35C-DS3R, this one was a suggestion from a mate and it does sound pretty good.

If anyone has any suggestions on GPU's to get and possibly a PSU that would be reliable enough to run the machine then please say so. Obviously it has to be a realistic price. Not something like $18,000 cards like that external Nvidia one lol.
