When I play games like Landmark, my game runs smooth for like a couple seconds, then the FPS drops way low for a couple seconds then repeats! I looked at my GPU usage, it's spiking up and down as I'm playing my game.

My CPU spikes up and down as well, but it stays around 75-100 and doesn't go much lower. It's pretty consistantly up there. So what's going on with my computer? Is it my CPU that needs upgrading or GPU?

P.S. I just bought a fx-8320 but i'm waiting to get a new motherboard.
