From what i can tell the 7800Go is 16/6 clock somewhere in the 350-400MHz and 1.2Ghz RAM meaning it will probably flat out beat a 6800Ultra. But i'm going to have to wait to get my dell in to see what it really is. A Go 6800Ultra is basically a PICeX 6800GS. A Go 7600 should beat a 6800V its 8/5 450/500.
