Hello all, I have a SB Audigy 2 ZS gamer. It doesn't work very good with my current OS and GB board. The drivers are outdated and one of my legacy games (BFVietnam) uses EXA (which is cool when used) as my other games suck too, sound wise. I'm asking for comments on a up-to-date sound card that can do 5.1 speakers, EXA, THX, Dolby digital and DTS. Price range up to $100.00. TIA!!
