Your X11 server will have a whole other core to run in if things get taxing. In any case, we are doing something wrong if gschem is consuming 100% CPU on one core, and X11 is doing similar! -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)

It runs on one core, no matter how many you have. So no, don't expect a big speed up.

Re: gEDA-user: going multi core
If the new system is anything like this list, you should expect a significant slowdown as the CPUs argue amongst themselves as to who gets to do what, when and how not to do something. I have not seen a significant advantage to single process geda tools execution. I suspect that some of the backend graphics might benefit. It is while doing long CPU intensive operations (FPGA synthesis) having the other cores free is really appreciated.
