So this morning as I'm shaving, I'm thinking about ways to get even more performance out of the MP - specifically when Snow Leopard comes out next year. Except for the 8800GT my other PCI Express slots are empty. Does anyone think it would make sense to go out and buy a couple of ATI 3870s from Macsales? I'm not looking to support more monitors. I'm thinking about this purely from the standpoint of offloading processor heavy tasks like encoding movies and such.
