I have an MSI board with the support to run both an nvidia and ati card at the same time, but I seem to be having some trouble getting them to cooperate. I'm trying to run an ATI 5770 as my main card and a gtx 460 as my physx/cuda card. Would someone mind running me through what all has to be done to get this set up to work please? Because at this point other forums that I have read and tried to follow haven't worked out, and for now I'm stuck with just running the gtx 460.
