Well, the Athlon series does not support dual processor configurations. You will have to look at the Opteron Series, or the Intel Xeon Series. If you really so desire, there are motherboards which offer 16 RAM slots, and four processor sockets. These configurations still will not give you the best desktop performance, but if you find some motherboards you like, send me the links and I'll give you some suggestions, I won't find any until you've decided on the CPU, and other factors involved. But I'll be glad to help out.
