is my CPU bottlenecking?

[almoststew1990]

I recently upgraded to an ATI 7870 from a 4890. I expected the frame rate at 'max settings' at 1920*1080 to increase massively in games such as metro and GTA IV, but I have gone from 30 to 50 or so in both games- lower than the review benchmarks suggested. So I am wondering if my CPU is limiting my performance. I have an i7 860 (1155 socket) clocked at 3.3GHz (stock is 2.8). So is my processor's age beginning to show?

ASUS P4P55D- EVO
i7 860
4Gb 1666MHz
500GB 7200RPM
Sapphire ATI 7870

Thanks!

Cheers for the replies guys. My cooler is a Cooler Master Hyper 212 Plus CPU Cooler (OCUK no longer sell it, so: http://www.coolermaster.co.uk/product.php?product_id=6603). I only have the one pull fan on it at the moment, should I get a second for push + pull? Will this be a good enough cooler or should I invest £40-50 on a really good cooler to get a better overclock?

In the low 60s I believe, I am away from my desktop for a while so I can't tell you exactly! It was never a cause for concern when I was testing in Prime95, I don't think it reached 70.
