Hi, I recently purchased a Gigabyte Radeon HD 7950 and have it clocked to 1120/1250.
I did a benchmark of it on Unigine Heaven 4.0 with the 'Extreme' preset and nothing changed and have been getting these scores:

FPS: 32.1
Score: 808
Min FPS: 16.1
Max FPS: 60.0

So, I was wondering whether this is normal or if there is something wrong with my GPU or if my CPU is bottle necking my GPU?
My CPU is an Intel Core i5-2320 @ 3.00GHz.

Thanks in advance.
