Fermi is going to have to be amazing to be worth a lot of money. We all know that if it turns out faster than the 5970 (which I'm 99% certain it won't), AMD will just slash the price on it.
There are other variables now too. Eyefinity might be a gimmick for some but to me it is the future of gaming and I reckon a lot of the usual top-end Nvidia buyers have fallen for that too.
Eyefinity is a gimmick
1 the 3 monitors have to be all the same resolution which from among my friends usually if one has 2+ monitors unless they were all bought at the same time they are different rez and different sizes.
2 you need 3 monitors or more which is a pretty rare set up to begin with
3 it's a gimmick because of that like cuda, yes it has it's use but it's hardly mainstream enough to be a true selling point to every user.
4 it doesn't prove an advantage if anything it proves a disadvantage by making you use your perphials but it is an experience. It's no more a valid seeling point then nvidia 3d stereoscopic crap.
I hope the GTX380 is better then a 5970 hell i hope it crushes all previous records easily, although i know that's def not the deal atleast like crushing performance diff it would be nice to have a powerful gpu, although knowing nvidia price would be 8800ULTRA costs lol
