Problems after overclocking GPU

[Marzstaa]

So I over clocked my GPU and everything was running smoothly but shortly after I turned off one day and did it another day, I've been some problems on one specific game only and that's World of Warcraft. I only over clocked by 10 which is normal I was told, but I get lag everytime I do something small. For example for any WoW players out there, doing BGs and Ashran is now super laggy for me but I never lagged doing those. Raids as well. What do you think I did?

CPU: AMD FX-6300 Vishera Six Core 3.5 ghz

GPU: EVGA GTX 660 SSC

Motherboard: ASUS M5A97 R2.0 AMD+3

OCing is a crapshoot, and its never guaranteed. If everything's fine at stock settings, then you're gonna need to up your voltage to achieve higher clocks.

And the lag is likely from an unstable OC.
