Please fold with your Crossfire and 3870X2 setups. I'm very interested to know if they work right out of the box with this new client. Unfortunately there is no fancy GUI with this one but FahMon is projecting 1330PPD which ain't bad for a GPU. Thats at 3D speeds by the way. You will most likely have to force 3D clock speeds with ATITool 0.27 Beta 4. ENJOY!
