Not a Windoz guy, but have you tried a different flash plugin ? Some earlier flash plugins had hot loops that would just eat all available cpu time.
Do you have the latest java install ?
Some versions of firefox (3.x) were leaking memory badly. I caught one at 4.9GB swapping and terrible performance ! But that doesn't explain the chrome & ie performance.
