""Is it possible to use 2 motherboards together?"
Yes. You would be running two independent computers in the same case. You would use cluster software to make the two computers work togather."
any clustering software you know of and recommend? Would i need a special case for this, or would it be possible to wire it together?
""would i be better off getting a dual processor motherboard(s)?"
If you have a dual processor motherboard then you would use a single kernel with SMP support. Which is better depends on what application types you want to run. Looking at the cards you want to install I would say that you would be better of with SMP than with a cluster."
well i'm looking to save money, and increase my computing speed/power... my friend's giving me a good deal on his computer.
thanks for your reply!
