That is a great comp seeing as though everything is new technology and the video card is the most expensive gaming card available. I personally would just settle for a 7800GT but opting for an X2 core instead. You will want to have a good power supply. You can usually tell which ones are better based on price but Enermax is generally a pretty reliable brand. You could also try Seagate S-ATA drives w/ NCQ. They are as good as they get for that price and comes with a 5-yr warranty.
