I was thinking of a 470 too. I can get one here in Europe for not much more than a 460. But the heat issues still remain. Although there will be extremely good ventilation in the case. It has 3 x 230 mm case fans and one smaller fan for back exhaust. I just get uncomfortable hearing about 95+ degrees. But maybe I wouldn't see anything of the sort in the HAF?
The 400 series seems like a great set of cards, minus the heat.
I'd get 2 x gtx 460, cheaper and better than gtx 480. If you get a 480 now, by time you'd need a second 480, much better options would be available. SLI 460 setup should seemingly last 2 years without hassle, irrespective of the better cards that would be coming through.
GTX470 is a quite cool card when you compared to GTX480.
You are just too afraid, i see you have a good airflow inside your case, so dual GTX470 shouldn't be a problem. Dual GTX470 should be lasting longer than Dual GTX460.
Well, your choice.
Between 2 GTX 460s and 1 GTX 480,i would go with 2 GTX 460s because they are about 20% faster than 1 GTX 480.
As for 2 GTX 460s vs 2 470s,well i would still go with 2 GTX 460s because the first ones run cooler,quieter and have less power consumption, also the performance difference isn't huge;furthermore, they cost less too.
However, if you are OK with more noise and power consumption,then go with 2 470s.
This will stay cool and also overclock well, since it was designed for that.
You will be able to add another one down the road and even if the cards are touching each other it has angled fans witch will help with cooling.
Looks like a nice card. Unfortunately I can't find it for anything near the price of the 460. I can get the Gigabyte 460 1GB here in the U.K. for 168 Pounds - the 470 one you link to is about 100 pounds more than that. I'm not sure if the performance would justify the extra 100 pounds...
Normally I'd say go with the best single card you can afford, however the 460 1GB is so impressive (alone and in SLI) I have to recommend it. As others have said, by the time you need more than 1 GTX480 or two GTX460s, a smaller and better card series will be out.
I just went sli 1gb 460, I know I will only have at most 1080p 1920x1080, so even though its not very popular, IMO, I could have gone with the 768 cards and saved a 100 dollars.
Newegg has a new gtx 460~768 msi twin frzer card for 180.00.
Anyways the cards are awesome, single Cyclone my o/c was 920/1050.
Now in SLI , its 895/990 . The top card runs at 66c in a constant Crysis Time demo, the bottom card 8 degrees less.

I use all 3, which ever supplies the cheapest item i need at the time, i have 2xGTX470's and agreed the first runs really hot, but nothing to get worried about, only ever seen mine get to 91oC, it still has 14oC to get to the limit, which i cant see it getting that close for a while.
