Hi, I recently bought a Leadtek 6800 GT which didnt fit in my dell system, the IDE slot kept blocking the rear end of the card. Hence, I must go with an ATI or a 6600, but that wont happen. So my question is: If I can get a x800 pro for 400 and a x800 XT for 450, is the XT's 4 extra pipelines and core/memory speeds really worth the 50 bucks? Thanx for any input I recieve.
