I've got a MSI HAWK 5770 the reason I bought that card is got it is the best 5770 (having researched) for OC'ing and cooling. I may at some point get another one if it will improve performance by 50% at least, don't know. The reason your GPU is overheating is because your cooling is failing it I suspect.
