So having a bigger framebuffer is now dishonest, but we should all wait for 2GB HD 5870, riiiight
GTX 470 looks like a great card. I think they will eventually match HD 5870 performance with driver updates, so the only question remaining is, if it will be in time before a refresh or a price drop.
GTX 480 results are all over the place. There's just too big of a delta between the slowest and fastest results. Any review tries to explain that? I don't really care about the power consumption or the heat. 93°C in load is not that far from my previous card. The only bad thing remaining is the noise and if all it takes is placing a 120mm fan on top of the card, then I see no problem.
If I had the money right now, I would buy one GTX 470 with the possibility going SLI some time in the future. But I just bought Xbox 360 and have plenty of games to go through, so I'll wait for a month or two and see, if drivers really do something.
