GTA V Low FPS on HD 7970

[MasterCheif0077]

I recently bought a Radeon HD 7970 to replace my gtx 750 ti. It was the the Sapphire version and so I went on the Sapphire site and got the latest drivers for it. I then restarted my PC and it was great. I was getting double the performance except in 1 game: GTA 5. I used AMD radeon optimising to optimise to their 'optimal' settings, and I was barely breaking 30. I lowered it to normal and I still was dipping into the 20's. I don't know why this is, as it is lower settings than my previous 750 ti. Anyway, I tried overclocking, which did increase my performance a bit (1050MHz core) (1500 memory) and I got around 45 fps on normal settings (1280 x 1024). It's a shame, because I can play games such as black ops 3 on extra while having the frame rate never dip below 60 and stay in the 90's. In addition, my gta crashes randomly, and then crashes when I relaunch, until I restart my PC. This crashing has happened on both installations of the game and before and after the OC. The GPU has never ever exceeded 83 degrees under load . Help please.
Also, here are my PC specs:
CPU: AMD A10 7870K @ 5GHz
CPU Cooler: Coolermaster Hyper 212x
GPU: Sapphire HD 7970
RAM: Kingston HyperX 8GB DDR3 @ 1866 MHz
PSU: EVGA 600B
STORAGE: Crucial MX100 256GB and WB Black 2TB (Where GTA is)
CASE: Bitfenix Prodigy White

You want to make sure all of the Nvidia drivers are uninstalled from your system, I would uninstall the AMD drivers as well just to clear out any corruption that might of happened. You can do it with a tool Display Driver Uninstaller http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

Remove any trace of AMD and Nvidia drivers with that tool and reboot the system. Windows might install some generic drivers and it may want to reboot again, if it wants you to , then reboot again. Download the newest AMD drivers and install them, don;t go to Sapphire's site for drivers as they tend to be behind on the versions of drivers. http://support.amd.com/en-us/download

Select the card and OS and download and install, Restart afterwards even if it says nothing about restarting, windows could still be on the Generic driver. If you still get low FPS, You might want to verify the game cache with steam, it might be trying to use Nvidia optimizations from your previous card.

No improvement. I think the problem is that my A10-7870K @ 4.8GHz is bottlenecking my HD 7970, as GTA is quite cpu intensive, whilst cod isnt. Thanks anyway. Also, the crashing was cos gta didnt like my 5GHz clock, so I changed it to 4.8 and it's fine. Still, 30fps sucks!

That doesn't look all that out of line compared to the CPU benchmarks for GTA V.

Though it also depends on your settings and such. I know back when I had a 7970 GHz edition running GTA V (though with an i7) I still had to dial it back to get near 60 fps. GTA V is a much better port than the previous game, but it's still on the higher-end of the requirements spectrum.
