I have recently installed Windows in my Mac with the intention of playing Skyrim, but I found out that my gfx card sucks. In fact, when I try to play Hearts or Solitaire on Windows it gives me a warning about my hardware acceleration and the game runs poorly. I currently have a NVIDIA GeForce GT 120. I feel I should upgrade this, but I don't have a whole ton of money (around $100 is about my spending ceiling) plus I have no idea what the hell I am doing. Any recommendations?
