Hey Guys, I feel something might be up with my 4850. I get some weird rendering in WoW (in OSX) and it doesn't seem to preform very well in COD4 (in Windows). Seems like these issues recently started. Anyone else have an issue like this? Seems like when I first started using this system I had no problems. I have installed latest drivers. I have SMCFan going on a higher speed to reduce heating. Done everything I can think of and stilll having issues. Am I missing anything? I'd like to find some sort of program (OSX prefer) to do a stress test on the graphics card if there is one if there is one.
