When I play games like BF3 and Skyrim, I get insane lag. I'm using crossfired Radeon HD 7950s and my monitor is a LG Flatron IPS235.
With BF3, the NPCs just stutter and I see lines in the screen occasionally. With Skyrim the lag gets to the point where the game is unplayable.
Is it my monitor or my GPUs? The monitor itself was around $300. I think its more than likely the video cards but I want some expert opinions on this. If it happens to be my video cards I was thinking about buying a Nvidia GTX 660 ti to replace my crossfired cards. Could it be just the crossfire configuration or are the cards just going bad on me? Should I try using a single card instead of a crossfire configuration? Is it my monitor? If so, what monitor/GPU do you recommend?
