Overall I would have to say I think they're pretty dissapointing products, haven't gotten a good look at the 470 yet but at least the 480, in my mind, is a pretty big failure. From what I've seen, the best case scenario is that it performs 5-10% faster than the 5870, and in the worst case equal or even a touch worse. For a 25% more expensive card thats coming to the market over half a year later, thats a pretty big dissapointment.
And as if that wasn't enough, a single 480 consumes more power under load than a 5970 for crying out loud! That reflects both on Nvidia's hot, inefficient design, and Ati's great acheivement with Cypress. Then you have to remember sticking a 480 in your case instead of a 5870 literally could raise temps 10C, I can't remember a card ever running this hot before. I've seen 93-99C in various load tests, thats just ridiculous, especially considering the heatsink this thing has.
Overall, I think its fair to say Ati is going to lay claim to this generation. Only thing I would have to say in regards to that is that Nvidia seemed to build the card around a feature that isn't enabled really yet, who cares if the 480 is a superior tessalator if the only place you see the benefits is the Heaven bench. By the time any games are out featuring it heavily, we'll have a new gen of cards out. Not necessarily Nvidia's fault however.
Edit- The more I read about it, the more the heat is bugging me. Seriously, this thing is SOO hot that people who have their CPU's OC'ed to about the edge of temp threshold might actually need to dial things back with one of these. I know I reach about 49C in gaming (Running F@H on the CPU at the same time, I bought a quad core and I'm going to use those clocks d@mn it!) and thats with my 4890 running at about 75-80C. Tack on another 10-15C to that temp, and suddenly I might be running at 52-53C, which is higher than I would want to run my CPU. And I'm very curious to see the F@H performance and temps, people are planning on doing some serious folding on these things lol, curious to see how long one of these lasts under 10-20 hours of constant 95C temps a day... Has anyone seen a review where they cover the temps of two of these in SLI? I have to imagine the top card reaches at least 100C.
