would this set up be profitable?

[dan0804smith]

if i got a bunch of older free computers and hooked them all up to be one computer (this is called a linux cluster)  would it be profitable to do this?  would i at least break even?

by doing this i would have ghz upon ghz of processing power, which is pretty much useless but whatever

i would have many gigs of graphix

i would also allocate all existing ram is Vram, which would be many GBs

what are your thoughts?

Not worth it in the slightest. My single 6850 could probably out perform all those computers and then some. You would probably pay like 5$ a day on power.

Please don't do it.  CPU mining is absolutely not cost effective.

In simple terms, CPU mining is nonsense, old Video Cards are useless.
The best Hardware is a ATI HD 4000, 5000 or 6000 series Card.
Also, fast NVIDIA Cards from 8000 series upward can do some Hashing.
