I'm not expecting to handle games like Skyrim or Crysis 2 without upgrading alot more, but I just want to be able to play games that look like my comp is just out of reach of playing (Like Halo 2, Trine, Spore). I was looking at an "Asus ATI Radeon HD6450 Silence 1GB Video Card" but don't know if I need to upgrade the power supply or anything else. Here are my specs:
