Is my CPU bottlenecking my GPU?

Hi I just bought an EVGA GeForce GTX 770 Superclocked 2GB and have been getting low FPS in games I should be able to run with no problem, such as Crysis 2 for example on High Settings.

My CPU is an Intel Core i5 760 that I was able to overclock to 3.4 GHZ. So could that be it? Or could voltage be an issue

I don't think it is bottlenecking to the point that you should have any major issues or have to spend a ton of money on a new board and processor.

Update your drivers, do a bios update on the board, and reset the CPU and see if that helps.

Also, what resolution are you running at? Lower resolutions (under 1080p) can cause a CPU bottleneck.

Test 1. GPU usage on GPUZ or something similar during gaming, if its 100% then its fine.
Test 2 Lower the resolution and check average fps, if the gain is minor then indeed the CPU is a lazy one.

The i5-760 is a very good processor with 4 cores and you were able to overclock it to 3.4 GHz and 8MB of Smart Cache. The i5 600 series only had 2 cores, so that was a big difference.

In addition your CPU ISN'T a bottleneck for your GPU by a long way.
You say low fps but how low? What are your expectations?

See if your motherboard bios is out of date. I had a similar problem with my evga 780. After flashing my mobo bios the problem went away. Be careful if/when you do it because there is some risk involved.
