A bit of a "Cliche" you could say but you can't really measure acceptable performance/spec by watching CPU usage go up and down in task manager unless you really have a feel for it. Dragging a window about will certainly raise CPU up, infact, just moving your mouse around rapidly will no doubt increase CPU utilization in task manager by 2-3% on a P4 system.
I have a feeling you don't have a proper graphics driver installed. Can you double check this?
Failing this, it might be worth a reinstall of the OS (or further diagnostic) because from your descriptions it is underperforming. Double check Paging file settings are automatic, purge system restore, run chkdsk, defrag disks, disable indexing service, ensure all drivers correctly installed.

edit again - oh, it did work, just this forum can't handle it before a quotation mark!
