Originally I had a Presario SR5410F, it wasnt working anymore for games and such. So I bought a ASRock 770DE+ motherboard, and a Athlon II x3 450 CPU, and a MSI R5770 Hawk video card. Kept my DDR2 memory 4GB(2x2). Bought a new case since the new board didnt fit in the old one and the case came with a 500w psu. I kept the hard drive and DVD drive from the Compaq. I am wondering what else i have left to do that would make any difference? I am thinking that with my current setup without starting over I would be better off buying a DDR3 board and some DDR3 memory? expensive yes but im just curious if thats whats left? Will a newer hard drive make a difference in performance? I am very happy with the setup now so im more just curious than anything I guess. so Im open to all suggestions. Cheers!
