Given that it only has a 256 bit memory bus, it'll have a serious disadvantage in memory bandwith compared to the HD7970 for one, and you can only use 8 memory modules( each uses a 32 bit interface) and the card packs at 2 GB or ram onboard, or 4 GB if modules with twice the density exist.(i'm not sure they do).
Then there's the GK104 designation wich as i mentioned in a previous post is usually reserved for midrange products, and the current fermi version(GF104) is used the GTX560 cards right now, so i could see this GK104 version probably get pretty close to the performance of a GTX580, and for 300$ it would be a no brainer really...
Mind you i'm assuming that the information from charlie is accurate as his hatred for Nvidia in general is pretty much legendary at this point....
