[Discuss-gnuradio] super fast gnuradio PC

[Achilleas Anastasopoulos]

I apologize for the slightly off topic.

I had just received a donation from Intel of
8 quad-core XEON processors E5440 and I was thinking
of building a super fast gnuradio PC system.
Does anyone have an idea as to what is the best way to utilize these 
processors to build a super fast PC system for gnuradio?
Are there any 4-slot motherboards?

Thanks for the advise
