Bonuses will be
-Great DX9 performance and Quality
-Mucho better FSAA
-Um.. cat 3.8's
-Will be 1/2 the speed of your 5800 in the majority of Games around today.
-You like SWG?? i am playing it to and at 1024x768 2x FSAA+8xAF with the "Default" graphics and terrain settings i get at most 25 FPS and at worst 12 FPS. During most game sessions.
Odly using 4x FSAA it is almost the same performance.
