Default XFX 7970 not working properly

Okay, So I just upgraded from my old EVGA 560 to this XFX Double D 7970 and I have not gotten any inprovment in my gaming FPS in fact I think I'm getting a few frames less then before, I've done a clean intall of windows and reinstalled the driver but I can't even maintain 60 fps in minecraft anymore which is really bothersome. Does anyone have any suggestions on what I could try?

PC & GPU info:

Heaven Bench Results:

Usage between 10% - 25% throughout benchmark
GPU Temp peaked at around 79C

1000w Power Supply

I've dismissed the idea that games arent optimized for multiple threads/cores because Crysis 3 ( A supposed multithread frendly game) also had the same problems when I ran it.

Your heaven benchmark doesn't seem too far off the mark. My 680 (when it works) does in the 40's in Heaven at High settings with Extreme tesselation. You may be CPU limited here. Have you tried overclocking and seeing what your results are?

I think he is saying his new card in the same system isn't doing any better than the old 560. I would think it's a software issue. Drivers perhaps. I'll do a quick heaven run.

Edit: OK ran the bench and got a score of 950 with those settings. My card clocks are 1100/1650 with Catalyst 13.2 Beta 7.

If your GPU clocks are lower than mine that would account for the extra ~100 in the score. So it does seem in line. As for your minecraft performance I would say try a known good driver that works well with minecraft. Unfortunately I do not have that game to test for you.
