If you switch to a DAC you'll lose most of the positional stuff for games, personally I wouldn't bother. If you do mostly gaming and want to pluck the card out, grab a USB equivalent with all the HRTF stuff etc. This is all without enabling any effects or anything on the titanium. Broad statement, but most of the things y'all refer to as DAC's are really just meant to provide a hands-off stereo out. So, that lends itself more to music than gaming. You could always run S/PDIF out of the titanium to a separate DAC if you're not happy with the noise or whatever from it being in the case.
