For the last year and a half, ATI have been the underdog when it came to top end performance, with nVidia truly ruling the roost with it's high power GTX cards dominating anything ATI could throw at them. However, now ATI are fighting back with their latest 4 series cards which promise to match the new 2 series from nVidia on performance, while beating them on price. Today I have a 4850 from the kind folks at Sapphire to try out. Let's see how it stacks up.
