With a volume right now at 2100BTC and counting, and thats just from one exchange, I would say alot of people are willing to buy them
I'm sure people are buying. But as a miner (both AMD and Nvidia), if you are buying at these prices you are out of your mind. MaxCoin is a miner's wet dream right now. It's only being held up in price by the fact that the only pool where AMD GPUs can mine right now doesn't really work (and no AMD solo miner either). I've got 1 GH/s on the AMD side, and nothing to show for it after a few hours while a single Titan has returned 1.5 BTC.
