Hi guys, I'm hoping you could help me out with this problem. Basically, playing any source based game(or any game in fact) I get low FPS. In Counter Strike Source I get FPS ranging from 20 to 40. Call of duty 2 can range from 26-50 FPS. I should be getting well over 100FPS in CSS with the 8800GT.
Spec:
AMD X2 5000+
EVGA 8800GT
2GB DDR 667mhz
Windows Vista Business 64bit
Being a poor uni student , I opted for the HP DX2250 just over a year ago for £180 and upgraded the graphics card and the PSU, but my framerates seem to be bottlenecked by either the CPU or memory I'd say but I'm not sure.
I can't overclock the CPU either, as HP lock all the overclocking features in the bios
. So guys, help me out here please! Do you reckon its the processor, the memory or is it just a big pile of poo that needs replacing? 
Any help is much appreciated!
