For some reason this keeps not posting correctly.
1)I need to upgrade my graphics card.
2)I need to upgrade my PSU to do that (probably).
3)My current PSU is a little over 300W.
4)I need to spend 100$ total, preferably less.
5)The upgrade needs to let me play High def video, and fairly recent games, like oblivion, and fallout 3.
6)I need to know how to tell which PSU's will be compatible with my computer.
7)I could use some suggestions for specific Graphics cards or PSUs.
Dxdiag in the spoiler.
