Hey new here and i have a decent computer and want to upgrade a few things. I have been out of the computer gaming scene for a while and want some suggestions on upgrading my current system..... I currently have a HP media center m7640n, AMD 64 X2 processor which is am2 socket, i want to upgrade graphics card, and RAM currently 2GB of ddr2 ram, and only 350w power supply so that needs upgrading as well. im not a gaming fanatic but i do love great graphics and was interested in getting an HD flat screen so HDMI is needed i believe. any suggestions would be appreciated. Looking to upgrade powersupply, RAM, and graphics card first and possibly the processor after i get the others.
