Low resolution? Graphics details lowered? You can have success with every card with vram bigger than 2! Again: clod is not about graphics. It is about vram and a balanced system with good cpu and suitable gpu.
A subjective answer like "my system runs it great" is not sufficient. Perhaps you do not see, what others do?
Some guys also say, that their gtx 295 runs great in a certain game. When I came to them to test, the microstutters were terrible. They do not see it! So this is subjective.
