I upgraded from my 6870 to a 7950 today and i expected a massive fps boost. The Benchmarks are okay, way ahead of my old GPU, but in games i gain 5-10 fps. so i searched google and all i could find were stupid people and driver sweeper. uninstalled the drivers, used driver sweeper, reinstalled, same issue. I also read that my CPU would be bottlenecking, but that doesnt make a whole lot of sense to me, the FX series isn't the best, but it isn't that bad.
7950 bad fps

That CPU isn't the best but it shouldn't be bottlenecking a single 7950. Could you post a link to a 3DMark11 run please?
See here for a rough guide on the fps boost you should be getting:

just an example: bfbc2 starts with the 60fps even a laptop gets in the menu. until i open the server browser. 15 fps madness. i'm going to provide a 3dmark11 run, but only the basic one. give me a few minutes, i have a slow connection. here is my heaven benchmark at stock speed (i did overclock it to 1050Mhz core, 1500 Mhz memory, already clocked back. same results in game)
but this sure is worrying

Just found someone with a 7950 and an i5 2500k and his results are the same as yours:

The benchmark is normal. Is it just BFBC2 which you're having problems in?

On old games where you're pushing very high FPS the CPU becomes the bottleneck so try to focus on GPU intensive games such as BFBC2. Which drivers are you running? If it's the latest version then it's more than likely a driver problem. On the other forum I use there's a thread like this every other day and 9/10 the card is fine.
EDIT:
Do a full custom uninstall of your drivers and choose to remove everything. Then install the latest drivers which are 12.10 found here:

here is my 3dmark benchmark. quite weird. http://www.3dmark.com/3dm11/5534269
already did that, but i'm gonna give it another try. 12.11 is the driver i use.
now i'm sure something isn't right. i started bc2 and my fps are about the same as with my old gpu, a tad higher maybe. then i log in and the same menu i had 60 fps in before only has 30 fps now. then i go to server browser and it cuts in half again to 15 fps! also when i'm in game and i open my scoreboard the fps drop by at least 30
afterburner. i dont use vsync at all. also with vsync i would be capped at 60 fps. i aint capped there. it's weird how the game starts with 80 fps avg and then just gets lower and lower until it is in the 40s. also why would the fps drop that badly when i open up the score board
