| So you know it's not really the sound system, it's the bloated,
| multilayered, inefficient XWindows system that's killing your CPU cycles.

Total FUD. XWindows is supprisingly efficient.

| and it's GUI is pretty efficient.

| the card, the more it can potentially offload from the CPU - provided an
| XWindows driver exists that will allow it.

Dude, do you know anything about video architecture? Most likely what is
occuring on your system is that the video driver that you have loaded for
XFree86 isn't accellerated therefore the CPU must perform all of the redrawing.
If you have your XFree86 properly configured you wouldn't have any of the
problems you've described. I never see CPU usuage go up with moving or resizing
windows.

| the desktop enhancements, and see if that helps.

Furthermore, changing window managers (Gnome, KDE, or whatever)will have no
affect on this problem.
