When I overclock my fx-8350 @ 4.7 Ghz my graphics card delivers lower frames, and there are like 1 second lag spikes and shutters when I play a game when i am overclocking, my gpu is a AMD Radeon 7970 Ghz Edition from Gigabyte, is this even normal. When I dont overclock and I am at a default clock of 4.0 Ghz - 4.2 Ghz I get smooth frames and wonderful gameplay.
