Just picked up SC2 and boy is it fun. However I am having a graphics card problem. I don't want to play a game on low graphic settings anymore. Money is not an issue, although I don't play SC2 religiously. My range is around 300 dollars for a graphics card that's very good and can play my settings on high/ultra. Here are my PC perks:
AMD Phenom(tm) 95550 Quad-Core Processor 2.20 GHz
64-bit Operating System
Chip Type: GeFroce 9100
Monitor: (if this matters) - ACER x203H 60Hertz
I hope this helps, I really would like to pick up a graphics card in the next couple days. Thanks!
