Thanks Ed, thats very helpful.
I'm running a dual core AMD +4400, and I know that a change to an intel
dual core is currently the way to go, but that means a mobo change too, and
probably the memory as well. I should have mentioned that I also use the
Matrox TH2G at 3840x1024 so GPU oomph will help. The GPU upgrade may be a
quick fix, although not particularly cheap.
Thanks again,
Rich
