this sounds like a dumb ? to me, but I got to ask, when you say clients, that is the F@H software, and I am guessing the slots are the gpu's? I ask about the clients cause I don't see much tweaking on the F@H software I have, is there something better out there that I can choose to only get the best wu's? And what kind of options are there for the slots to increase workload efficiency? I might be looking in the wrong spots, but other than over clocking the GPU's I thought the only other thing you might be able to do is gut the OS so its as streamlined as possible?
