I decided on buying a second graphics card instead of getting a more expensive and more powerful singe graphics card. The problem is though that any game I try to load up either doesn't get much past the splash screen or I end up with terrible stuttering, tearing, and flickering. I have two EVGA 760 FTW 4GB cards on a MSI Z87-G45 mobo. Any suggestions on how to fix this would be greatly appreciated
