i have this
Newegg.com - Creative SB X-Fi Xtreme Audio 70SB104000000 7.1 Channels PCI Express Interface Sound Card - Sound Cards only 60 bucks and sounds great! the only thing is when i first put it vista was almost unusably slow until i installed the drivers. after that it got back to fastnes. and the first week i had it i would experience crackles and pops. but like slowness it got better and i havent herd a pop since beginning of august.
