You've got a good collection there though. I don't put any cpu's on it, just running gpu's now and then. I plan on putting more effort into it though. Put a GTX560ti on it this evening. I had also picked up a GTX460, but on bringing it home it turned out there is bad memory in the card so that will be going back to the store. Then I also have a GTS-250 that I run now and then on it. It still works better on the stuff than the ATI gpu's. lol So I will proly pick up a couple more lower end nvidia cards to replace some more ATI's and cut down on the heat a bit.
