I'm building a new PC and this current PC will just be sitting around for the time being. I'd like to throw an AIW in here to use the system for capping TV as well as using TV output to play emulated games, DVDs, and (S)VCDs. I was wondering if there is a difference in quality in the TV I/O and capturing between the AIW Radeon and the AIW Radeon 7500? Obviously the 7500 is faster for gaming, but that's not a concern.
