Can anyone tell me if these are any good for mining?  I know people are buying them because as soon as they were announced, they were sold out in minutes, but I'm debating buying some of the next batch. 

However, I've heard mixed reviews of the VisionTek brand as a whole, so I don't want to go buying into unknown technologies here.  Anyone here one of the lucky folks who bought into the first batch and can tell us what kind of hash-rates you are getting?

For Bitcoins, ASICs are what you want.

Is there a reason why you are looking at a graphics card instead?

Those are useless for BTC but great for Scrypt based coins. The problem is, they use around 300 watts per card. So, depending on your electricity costs, they might not be a viable solution. (Unless you want to support the network and buy and hold.)
