So, my Radeon 5770 was overheating and shutting down the computer. For the foreseeable holiday season, I'll be using a new EVGA NVIDIA GeForce GT 520. It's using SO much less heat. It's not giving me as good on the performance, however. My question is, can I tweak the card settings to run the game better? If so, how and to what? Much appreciation would be given if someone can help me out. :P
