thanks in advance - i have a gigabyte geforce 6800GS and I would like to upgrade to geforce 8 when they come out next year. Insted of wasting the 6800 can i use it as a dedicated PPU? will nvidia provide driversfor this? - I have the MSI K8N Master2 FAR motherboard - with SLI. thus if this were possible i would be using one pcie slot for the geforce 8 and the other one for my geforce 6800 with will be processing physics insted of graphics.
