Thanks for your help. I do know I'll loose alot, but it's a question on money, and unfortunately I'm tied to buying from HP, which only use Xpress chipsets. It's quite a prediciment.
Would I gain much from switching to and ATI GPU, what kind of differences am I likely to see? Which one should I go for?
Depends on the card, just stick with your GeForce love-affair, it will be fine.
