Best price/perf. dual CPU system

[Stefpet]

Need some help here...

What is the best components for a dual CPU system considering price/performance ratio (with emphasize on price)?

CPU and motherboard recommendations appreciated. Thanks!

Depending on price I may need 5-10 machines in a compiler (GCC) farm. However, I rather get some more cheap than a few expensive. (and no, it's not for my personal use... )

Last I checked it was MP2400s on a Gigabyte dually board. It's the GA-7DPXDW-P (Or something very similar). I have one with some 2800s in it.

Very nice, and only about $550.
