Lets say I have two old computers sitting around. I want to create a computer cluster so that they two computers together can have more processing power to possibly be able to run old games faster than either of the two of them could handle alone. Does anyone have some experience doing this? Know of any good sites depicting people taking old computers and clustering them? I don't have two computers at this time to do this with but I think it might be interesting to do in the future with my antique hardware.
