Yup.  My desktop shows 4 CPUs although there's only two physical CPUs. The
difference is that the CPUs have Hyper-Threading which the OS treats as a
separate CPU.  It only speeds some operations, however, and certain apps may
actually go slower with its use.

I assume you mean the CPU is 50% used, which would be true if BW is chewing on
a CPU without a throttle to make it behave better.  On a single CPU machine,
this would mean that you're near 100% CPU utilization.

The screen updates have more to do with the graphics chipset than the memory
speed.  Yeah, the FSB will help if it's using shared RAM but it's the chip that
makes the real difference.  I can tell the card in my desktop needs updating -
some graphics operations such as DVD display are sluggish.  It's not that old
or wussie a card, either, but it's apparently not enough.  Good thing I don't
care if DVD playback has issues (I just use it to test written DVDs)...
