From what I've read, I'm not going to see any gains in the processing power going cluster or any other method. Best I can hope for is to use them daisy chained as render nodes.
Btw, my initial question should have stated " multi use" not multi user. I'm looking to create the best I can from these three comps, (if worth while), for multi media type creation. Music, 3D modeling, animation, A/V editing and Special FX.
I have nothing now... Except these stock Dell comps. Memory costs, looking last night, to bring just two up to 32gig is high at around $400 for DDR3L... Two GPU's... One PSU as I have a new one already... I don't know.
Any thoughts, or should I just trash them and look for something better suited?
