You certainly could be right, but it won't work for me. I've never been able to put both ATI and Cudas on the same project. The scheduler in BOINC is so stupid it will wind up filling one card or the other over time till it reaches the project maximum and letting the other run dry. It is really frustrating to see the Cuda out of work and BOINC keeps asking for ATI wu or vice versa! I talked to Slicker and he said the problem was with the scheduler.
