Well, it looks like some companies just can't wait to announce something. I just got an email in my inbox from Newegg about the
GeForce GTX 580 being available. If
you go here, you can check out all the cards from eVGA, Gigabyte, PNY, and MSI. This is labeled as the fastest DX11 card on the planet and you can nab one for $559 and up, which is a good deal more than the MSRP I was told last night.
I'll have my quick write up on the card in a few hours but if you're interested in purchasing one now, you can do so.
