So I've a old desktop, that wanted to upgrade but a need some advices to do it. The basics. Motherboard: Asus P5GC-MX/1333 CPU: Intel E7200 2.53Ghz running @3.05Ghz RAM: 3GB DDR2 GPU: Nvidia 8500GT 1GB PSU: Lcpower 420w My real question here is can I upgrade to a Nvidia 660ti, and the power supply to a 620w seasonic, until I buy a new motherboard, cpu and ram. I know the gpu will be bottlenecked, and is that gpu enough for photo editing (photoshop mainly) and some games (not ultra setting but all in the market right now) Thanks for your help
