I'm going to give this old pre-built rig to a friend as a birthday present but I want to beef it up a little before I do. I want to at least give it a better GPU but I am inexperienced with AMD. What could it handle without bottleneck? Any other recommendations? He will be running it on a 720p monitor and I am hoping for a steady 60FPS on medium-high settings if at all possible.
