I'd take a normal 8500 over the Ti500, not the LE. They aren't even in the same category, as the 8500 is cheaper than the Ti500.
I wish people like you would stop posting actually. ATI drivers were buggy in the RageIIc days, soon as the Rage 128 hit, they reworked their drivers, and I have never had a problem with them in anything. This included Rage128, Rage 128pro, Rage Fury MAXX (which should be the most buggy, but no problems), Radeon LE and the 8500. I have yet to expirence these bads drivers everyone talks of, and I know its pure BS. Issues wise on messages boards, both cards have rougly the same # of topics, and most can be worked around for both cards.
According to Tom's hardware, the tv-out on the Ti200s was absolute crap, and had major driver problems. Since they are basically the same card, I'd guess the Ti500 has the same thing, and I'd avoid it. Nvidia might be good at giving you stable drivers, but it takes them a long time before they get new features right (personal cinema, tv out, intial gf3 release is proof enough)
