Hi I just started playing the game recently and noticed some glitches when I was in Test Center trying out 1.2 Patch. Here is a brief description of my PC and a link to a more detailed one. I would like to know what would be the best Graphics Card, Power Supply and/or Cooling System (if needed) to upgrade my computer so the graphics will work better. Thanks for your help
