I owned the first personal cinema that came out, based on the mx400, the external box with the tv tuner and connections is a great idea, and the tv tuner had really good picture and quality. Gaming it was a little week, with that and my old tbird 850mhz, i could only run today's games "QIII, UT2003, GTA) in 800X600X16bit... I had an original radeon AIW before that, and it was awful, kept crashing my computer. But ATI's drivers have come a long way since then, and that was on 98(NOT SE).
Mudd, you said switching to a radeon made your colors more vivid? Mine got less vivid on my monitor, I just got a 9500PRO a few weeks ago, my mx400 was much more vivid, and it had the setting for "digital vibrance" or something, that beefed up the color a lot. Does the radeon have a similar setting?
