Dual CPU System Question

I have a dual-cpu system with Fedora Core 1 installed, running kernel
2.4.22-1.2149.nptlsmp. The system has 2 2.0 GHz XEON processors, 2 GB
memory , yet the GUI seems rather unresponsive at times.
I noticed that /proc/cpuinfo yields:

While I would love to have a 4-cpu system, I only have 2...
Why are there four processors listed [RH 9.0 lists 2]? Could this be
the reason that the UI seems unresponsive?
When I say unresponsive, sometimes the mouse doesn't track smoothly,
window repainting is slow. I recognize that the graphics card could be
to blame [its a G450 dual head card], but I don't see the same
unresponsiveness under 9.0.
Overall, I have run applications on the dual CPU system that are,
overall, outperformed by a 1.6 GHz laptop....
Thanks!
