@emj - XFX Actually allows for people to Overclock their GPU, and they'll warranty it still if something messes up, as long as you don't touch/mod the Voltages which are actually locked, you can always send it in for a warranty repair/replacement, but yes, I have overclocked it after I experienced loss of performance, and didn't see any increase really, so I reset it to normal stock speeds again.
@woltej1 It's performing less in the same games that I've always played, BF3, FC3, etc.. I've done a clean install, any everything, I don't know what the problem is, I just got this GPU like three months ago, so hopefully when I call XFX tomorrow they can help me figure this out.
