If he sees a drop in FPS then it's obviously your GPU. If not then consider all of the factors. What kind of ram do you have?

It's also possible that your bottleneck is due to your Northbridge on your motherboard. The Northbridge handles the transfer of data to and from your RAM and PCI Express devices. While I'm not sure this is where the problem is, it's always a possibility.

I have 5gb ot patriot 800mhz ddr2 ram and vista 64bit. How would i check if it is the northbridge cauaeing the problem.
 
Yea i have no clue of checking northbridge either............

I caught on to something though, you said that at 1024x768 you were getting around 20 FPS when your friend got 60. Then you said that you tried 1600x1080 or something like that and you got 20 FPS once again while your friend got 30 FPS.
SHABAM, there you go, a clear indication that your CPU is bottlenecking your GPU. You get aroung the same FPS when going to a higher resolution, this is a clear indication of the CPU bottlenecking the CPU. So its definitly not your GPU i believe.

How is this a clear indication? If the GPU is not able to operate at it's full speed due to a bottleneck at the north bridge then it wouldn't matter what resolution he was running.

Anyways, I want you to run a couple tests for me. Go and download OCCT from here:
http://www.ocbase.com/perestroika_en/

Run it as administrator and then do the GPU:MEMTEST. Just click the ON button once you have that tab selected and allow it to run it's tests. This will detect any GPU Memory defects.

Then once you've completed that run the GPU OCCT and I'd let it run for an hour. Click on Error Check and then click the ON button.

Also what kind of memory does your friend have? And is he also running Windows Vista?

Torzak: What is your RAM configuration (Ex: 2-2GB sticks, 1-1GB stick) and what are your RAM timings (Ex: 5-5-5-15)? To me, 5GB seems like an odd number for RAM.
 
I am also curious about what your RAM configuration is. You are obviously not running dual channel, because there are not 2.5GB sticks or 1.25GB sticks. Utilizing dual channel could give you a performance increase.
 
i think the only thing that would make such a significant difference, which 20 fps (double the fps) is, is your cpu

Yea but its a freaking common sign of bottlenecking when you run the same FPS on a lower resolution as you do on a higher resolution. Its pretty obvious and exactly, if he has defected memory which doesn't allow him to run the GPU to it's full potential, then why is it running the same FPS at a higher resolution when the GPU is being strained more??? wouldn't it get less FPS??
Ill show you benchmarks of what bottlenecking is man.......

There you go....bottlenecking right there.
In COD5 and fallout 3, that flat-line is bottlenecking. FPS is supposed to decrease as the resolution increases, in these cases as well as torzak's, the FPS remains generally the same thus indicating a bottleneck.
Heres a quote "see that flat line? We ran into a bottleneck there, the 3.75 GHz clocked Core i7 965 processor isn't coping with it any longer."
 
Either way I've made my points and I'm not going to continue this back and forth.

@Torzak - The ball is in your field now. I hope whichever decision you make gives you the FPS boost you're looking for.
 
I cant do the mem test till next weekend because i cant get on my computer till then. As for my RAM configuration I have 2x 2GB and 2x512mb. Would I be better of osing the 2x 512mb and just using the 4GB?
