First, did anything else change hardware-wise aside from the graphics card?
Second, did any game settings or resolution settings change after installing the HD 7950?
Third, you installed the drivers that came with the Sapphire card. Uninstall AMD Catalyst via Control Panel, reboot, use driver sweeper to clean AMD-Display, reboot, install the latest AMD drivers (12.8), reboot.
Fourth, make sure you're recording your FPS on the same exact situation. When you're recording FPS, you can't record during different scenarios, they should be mostly the same. That's why benchmarking software is used a lot, everything remains consistent except the hardware (and/or drivers).
If you do all these steps and you're still having issues, then the problem is probably your HD 7950.

I fixed the main issue of fps being low and underperforming. It was a driver issue, things are nice and smooth now. Like Ive said in a few previous posts its now just me trying to figure out why it shows my gpu usage swapping at what seems to be clockwork timings from 100% to 64% (this isnt affecting my performance as far as I can see I just want to know why).

Driver sweeper is a nono these days because it seems to do more harm then good, at least this has been my experience. I use this guide and it does the trick quit nicely - http://www.overclock.net/t/988215/how-to-properly-uninstall-ati-amd-software-drivers-for-graphics-cards

Ummmmm anyways.

Ok all seems to be good now so I tried to do an OC of 1000Mhz core on stock voltage and as soon as I go in game it shows the core drop to 700 then to 600Mhz and my fps drops drastically. It is changed to 1000Mhz and this is verified by GPU-Z / AB.. As soon as I put it back to stock settings bam it goes to where it should and my fps is good again.

Basically it wont OC properly. As soon as I try my Clocks drop in game and performance goes to crap. Only doing 25Mhz at a time and the first 25mhz wrecks everything.

it's long been known the 7870 and 7950 are neck and neck in terms of performance

tha would be an unstable OC....throw some voltage at it...nothing major.. just a notch or 3 lol

How are you overclocking it?

At the same clocks a HD 7950 will be clearly 30% or more faster than HD 7870. HD 7950 (1.15 Ghz) will be 20% faster than HD 7870 (1.25 Ghz)
