poor gfx performance

[BigRoger]

i have a bfg 7800GT 256mb and when i play games i get really poor perfornance. When i play css i get 37-25 fps with everything on high and on dod s i got anywhere in between 40-15 fps everything on low.
Ihave tryed updating drivers and all that but i cant figure out what the problem is can anyone help.

What games have you tried? Try running 3dmark and see if your scores are low too.

Got any background apps running? Service pack 2?

Make sure you've plugged in the extra power supply cable into the graphics card - if I had a quid for the number of nVidia graphics cards owners that have complained to me about poor FPS but I find out that they are starving the poor card of power.....

I know it's an obvious one, but lets establish that you've done that first before we look elsewhere

I didnt think the machine would boot if it didnt have the power cable in the graphics cards.

try updating your mobo drivers and graphic card drivers

i have put the gfx power cable in and updated both mobo and gfx drivers i cant think what the problem might be
