Excellent news, I guess I'll continue working with my onboard audio to see what I can get, sounds promising :) As for my video, I broke down last night and bought an FX5200, supposedly this is a great card for doing HDTV decoding through XvMC. I found a matrix that isn't completely accurate comparing the different cards, but it seemed accurate enough for me to pick a decent card. Thanks for the reply!
