gaming, and then going to do graphic design in engineering
currenty i have a nividia 260 and a ssd 16gb
you might want to go for a quad core, e.g. Athlon II X4 620 - 640 very good processors, and you might require them for graphic design etc.
eh i took out the psu and replaced it with a Antec EarthWatts EA750 750W Continuous Power ATX12V version 2.3 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC "compatible with Core i7/Core i5" Power Supply. plus the phenomII x 4 952 is slightly better then the Athlon II X4 620
yeah, the phenom II x4 has cache L3, it makes quite a difference. (do you mean phenom 925 or 955?)
