Hi recently I got a New ASUS Geforce GTX 760 to replace my old 550 TI.
However I find that in some causes my games now perform worse or the same as before. I would like to know if this is because of my CPU or just driver issues. I will list my PC specs below and games im having issues with

Games

    Need for Speed Most Wanted 2012
    Assassins Creed IV Black Flag (towns lag while ship battles are usually ok)
    Battlefield 3 (Running at medium below 30 FPS)
    Sim City (lags a bit no matter the quality leading me to believe it is the CPU)


Specs

OS: Windows 8 Pro 64 Bit

CPU and Motherboard: Asus M4A88T-V EVO USB3 Motherboard and AMD Phenom II X4 955 Black Edition Quad Core CPU Bundle

RAM: Corsair CMX4GX3M1A1333C9 XMS3 4GB DDR3 RAM - PC10666, 1333MHz, 4096MB

I will ask the obvious. Did you uninstall the old drivers before slapping in the new card?

No I don't think so I just imideiatly went to Nvidia Geforce Experiance and installed the new drivers there.

One thing to mention however is I also had a AMD Radeon HD 4XXXX for a bit as I sold my 550 ti.

Remove your old drivers and install new ones.
also some graphic cards only flex their muscles at a higher resolution so try increasing your resolution.

I deleted all my old Drivers and reinstalled the new drivers and I still see little performance change with FPS in AC4 Towns still dropping to 20s and Need for Speed Most Wanted nearly unplayable with low FPS even on lowest graphics quality when Geforce Experiance says I should be able to run it on Ultra.

All of this is leading me to believe it is my CPU

Thanks everyone for your help but I think I found the solution.
I was thinking maybe a CPU upgrade or even overclocking would help. Then I noticed I only had 3 cores displayed on dxdiag and CPU-Z. So I opened my BIOS and sure enough core 3 was disabled for some reason.

Everything is now running smooth
