So I bought a computer from Best Buy (model p6674y: Phenom II 820x4, 6 gigs ddr3 ram) about 6 months ago, put in a 600w PSU, and a 5670 graphics card. I'm now considering upgrading my GPU to a factory overclocked gtx 570 (the specific card im looking at has posted dimensions 9'' x 4.38''). My power supply seems to be OK for this card from what I've read, but I'm concerned I may not have space to upgrade. Specifically I'm concerned that my RAM modules might be in the way. Can anyone take a look at some pictures I took of the inside of my computer to offer advice? I'd really appreciate it!
