Shew... I currently have the 4870 and am looking to upgrade to the 5870 for two reason: 1. I have duel ACD and need the dual mini display 2. I am an avid After Effects guru and need all the punch I can get (yes i know the QaudroFX, but it's just not worth it and they never update them). How do you all think they will compare performance for price? Any early reviews comparing them both on the PC at least?
