I have a Gigabyte Ma78lm-s2h motherboard with AMD x4 640 CPU Radeon HD6870 video card. When I play star craft I will get down to 0-6 fps. I don’t think it’s the video card that the bottle neck. Not sure what the issue is because I had an Nvidia 9600gt and received the same performance. When looking at my CPU I am only using like 25-30% so I don’t think that is the issue If I would upgrade the Motherboard to an AM3+ which has ddr3 would that make much of a difference? I am not sure what the issue is anyone has any idea how to make it run better?
