powercolor 7950 running slow

Hi I just got an 7950 yesterday, I was in need of a new card and I wanted to try out an AMD card for once. I got it installed the latest drivers from the website and then tried out some games. I tried out world at war zombies and it had a bad frame rate, don't know why since my old gtx 460 could easily max everything out and play with no lag. The only thing I can really see improvement is that it can get 80 fps in furmark, (40+ compared to what I used to get). Please help!

My specs are:
core 2 quad 8300
3Gb ram
G31M-GS R2.0
HD 7950
700w power supply

P.S: I'm getting new parts like a week from now, (i5,8gb ram, new motherboard) so would that make any difference in the performance in the card? Thanks for your time.

Your new parts might play into it yeah. That CPU is getting pretty old and I'm pretty sure 3GB was the gaming norm back in 2006? Doesn't explain the problems you are experiencing though. Might want to try that 7950 in another gaming rig if you have the chance. As long as it isn't even older than yours.

Other than that, do a clean driver uninstallation and run Driver Sweeper to get rid of any remnants of Nvidia and AMD drivers. Restart and reinstall newest AMD drivers. If this doesn't work, wait for the new parts and do remember to install 64-bit OS to make use of that 8GB of system memory. See if your GPU usage is unnaturally low. It should be an effective 100 or 99% most of the time unless you've limited your FPS in some manner, your CPU reaches 100% usage or 100% of system memory is being used at once, all of these will start throttling your graphics card down.

I reinstalled windows yesterday anyways and reinstalled the drivers from the disc this time and then upgrade the drivers, havent really tested it out much today but I did try furmark, still get 80 fps, but I need to try and actual game or benchmark. Any ideas I heard unigine is good. I also thought it was my old parts holding it back.

You can find out by checking your CPU/RAM/GPU usages during heavy load where you experience some bottlenecking. A CPU or memory bottleneck is the most likely culprit here as Furmark places extensive stress on the GPU and pretty much the GPU alone, unlike benchmarking utilities or games do.

What I still don't understand is how that would have a negative effect on your FPS going up from a GTX 470 at the same settings though.

You are running into a CPU bottleneck.

For now it seems like a bottleneck, my parts should be shipping by the 10th so if its better then Ill post.

Here is a recent review/analysis comparing the last 3/4 generations of cpus from intel. Check it out. http://www.tomshardware.com/reviews/ivy-bridge-wolfdale...
