Well thanks a lot for your help, mate. Being in the UK, I can't call XFX now because the offices are shut, so I'll have to do it in the morning.
Although Doom 3 IS very GPU-orientated, no arguements, I'm sure the reason you get a better FPS is down to your CPU. Bearing in mind that my card absolutely cuts through Far Cry, all settings maxed out at very decent framerates. So if I could somehow test my card and Doom 3 out on a faster system, then I'd know for sure...
