Hi all, just joined so go easy, just acquired a optiplex 745 small form, and want to uprade the graphics can anyone recommend a cheapish one, i have seen a Dell ATi Rage Ultra 128 Pro 16MB AGP Video Graphics Card VGA GPU Half Height, but have no idea on whether its better than the on board or not, or if there's better, im on a 15 inch monitor at the moment but looking to go bigger when funds available, also does the on board resolution which is set at 1024 x 768 and wont go any higher, set to the 15 inch monitor, all drivers are up to date and running, win 7, 2.5gb ram, 3.4 x 2 processor.
