Mini cluster of 2 PCs, possible?

[Jonny]

I know this is probably impossible, and would be done alot more if it was possible, but, if I had two PCs similar to those in my Spec, would it be possible to rig them both together? Maybe with a short optical network cable?
So that they kind of "shared the workload" and therefore ran my system faster?

Not for general use, but for compiling, and certain tasks yes. google distcc and beowulf clustering
