Looking to buy 2GB of DDR2 RAM, used or new I don't care, but it has to be fully functional. Also want an HD4670 1GB card or better at a low-decent price tag, and possibly an upgrade from my current 4200+. Note that I'm using socket 939 and not AM2. RAM/GPU are the two most important things right now, I want some hands on experience before building my i7 rig. I'm going to give this computer to someone after I finish building my rig, so it'd be nice to polish it up a bit. Since I'm giving it away, I'd like to spend the little as possible on the upgrading. Edit: This is a store bought PC. I just realized that I'm going to have to upgrade the PSU to at least a 550w.
