If you run a P4 system with win98 it will only run at 800Mhz.
besides as far as multi tasking goes, i usually have 15 - 20 things going at a time. i will often have BG2, adobe photoshop6, adobe imageready 3, 6 or 7 internet explorer windows, outlookXP and any other application which i happen to need at the time (plus the usual MSN messanger, Aim , or whatever)
If your having those troubles multitasking then i would suspect that you have something wrong with your system, and would recomend a reinstall of the os.
