Not sure why 56 is listed already, shouldn't actually be any out there. My impression was those came out on the 28th.
Usually when I use nowinstock Newegg would update too slowly and be out of stock by the time I was notified, but Amazon seems to work quite well.
Neat to see the Quadro P4000 on there. I might pick one of those up a few years from now just to have one. Why Nvidia doesn't make a consumer version of that I have no idea, but I would totally get one if they did.
