Yes, gaming is the priority, I play mostly DX9 era game, will be building a PC for later games soon so I'm only looking to improve on the 9800GTX, my monitor will only go up to 1440 x 900.
Playing IL2, Silent hunter 3 and Rome Total War at the mo. Will move on to high end gaming with the new build, hopefully R2TW.
I'm not familiar with the ATI series cards, and I wonder how well they'd work with my motherboard, would I need to update the BIOS? And how easy is it to clean the Nvidia drivers off the system?
