can you tell us which O/S you are using, this will enable us to research your problem more in depth.
I just finished installing a new motherboard, CPU and graphics card, but instead of enhancing my machine's ability to run games it seems to have taken a flying leap backwards. Even on relatively old software like Neverwinter Nights 2 my FPS is in the single digits, much worse that it was on my three year old hardware, and I have no idea what's wrong at this point.
My hardware is as follows:
Graphics Card - NVIDIA GeForce GTS 250
Processor - AMD Athlon 64 X2 Dual Core
Motherboard - ASRock K10N78 with a GeForce 8200 chipset
2 gigs of RAM
My drivers are up to date, my hardware's installed correctly. It seems like everything should be working better than ever, but it's actually worse with the new gear. And I have no idea why.
