Well I'm not much of an IQ (interpret that as you want ) guy but when I ran UT GOTY on my bro's 2400XT I have to say it looked way superior to my Geforce7 serie card. But GF7 is known to have relatively bad IQ anyways but GF8 has improved it and today there shouldn't be big enough difference for most people to make any difference. But back in the GF7 vs X19xx days ATI had a clear advantage.
