HORRIBLE! If you heard Vortex2 in Win98SE and loved it, you'll be dissapointed in XP!
Plain drivers. No quad (4 speakers). Sounds very bad.
Sound drops and cracklings but there is a fix to this sound drop using WPCREDIT - Try checking the VortexOfSound.com website for fix.
No Vortex control panel. Just plain bad sound - like your vortex 2 will sound like an AC97 from motherboard built in.
I suggest go dual boot - Win98SE or ME for games and WinXP for work.
Good Luck!
