Personally I'm loving the 470 - runs reasonably cool (maxed at 80c in furmark after 2 minutes), the fan is much less annoying than my 4870's, IQ looks better to me and gameplay seems much smoother - mostly due to higher minimum fps near as I can tell.
So far I can max almost every game also, except Metro, haven't messed with Crysis yet.
If you plan on overclocking it you can come close to meeting or exceeding a single 480 for a good bit less cash also.
470/480 are excellent cards, runs much cooller then my 280.
