So I'm putting together a new system, intended almost completely for gaming. I hope that it can last for a few years so it can last through college and until I can get a job. I already have a TX750 PSU so I don't need to get a new one.
Just a few changes: The RAM, like outlw suggested. Also, I would change the hard drive to a 1TB Samsung F3 Spinpoint, which is cheaper and faster than the WD drives right now because of the higher platter density. I would also suggest changed the motherboard to the ASUS P7P55D-E PRO. It's a great board for only $40 more, and it also has the new USB 3.0 and SATAIII ports.
