Yeah man. There was a fairly "wow" transition from Composite to S-Video, but I don't know how much of a difference RGB would make...

The bigger issue is that if I upgraded to RGB it'd be because I were streaming my SNES games for a show or reviews etc. With everything I listed about PLUS a DVI or VGA capture (for which the capture cards are like $2000 a piece... crazy...), I'm looking at about $2500 just to get a bump in streamable video quality, vs. now, where I can already capture S-Video with my Dazzle DVC100.

It's a shame that SCART was never implemented in the US and that it's such a pain to get usable RGB out of NTSC SNESs, even if it is a model 1.
