Ok so I did some reading and I am APPALLED at the POOR folding performance ofthe HD4xxx series.... those cards are MONSTERS by raw processing comparison. Goes to show, when software is NOT optimized for tech it SUCKS. Hope they sort out that problem and get the 800 Stream processors in the frey. As a side note, if you look at the Folding @ Home stats wrt types of clients and FLOPS, the GPU has 953 Teraflops from 8666 processors, vs. ANYTHING else be it windows, mac, PS3, etc.http://fah-web.stanford.edu/cgi-bin/main.py?qtype=osstatsGO GPU's!!! now all they have to get right is a console client and the ability to run mulitple GPU clients on the same machine. For those with SLI/Xfire.
