The features and specifications aren't must different from those of the vanilla Radeon HD4850. I still see GDDR3 RAM, 7.1 audio, and DirectX 10.1 support. The biggest different in the Toxic is the overclocking, the stock HD4850 clocks in at 625MHz GPU clock, and 1986MHz memory clock. The HD4850 Toxic is clocked 50MHz faster in GPU speeds, and 2200MHz in memory. Will the overclocking make a big difference in performance?
