I haven't updated the drivers on my ATI 8500 AIW since November on my bedroom's HTPC. The drivers are 126.96.36.19997 and seem to be stable. I just got a new 50" plasma and switched from ZP to Theatertek and figured maybe I'm missing out by not having the latest drivers... but then again, I've always figured if it's not broken don't fix it. With powerstrip, I've got beautiful 1:1 pixel mapping. Should I bother installing the new drivers? I know my card is old, btw, but it's working fine for me.
