This problem is also evident with a clean 8.10 64-bit install on a Dell Latitude E6400 laptop with nVidia Quadro 160M (using 177.80 driver).

Xorg, firefox and compiz are all using more cpu than they should when completely idle. Xorg is the worst offender and can use a full cpu core when scrolling a window (graphic or text) or when simply moving the mouse around a lot. Firefox is using about 3% cpu when doing nothing but displaying this page.

8.10 in general has a more sluggish feel than earlier releases.
