Saw something curious on Simplevert this evening, figured I'd see if the collective knowledge of the community could shed some light for a hapless newbie.

There is an address on there that is clocking in at ~300 MHash/sec between four different miners (150, 50, 50, and 50 MHash/sec each). I have a rig with 4X 280X and I'm running at ~1.4 MHash/sec. This would imply that the smaller three mining rigs would be in the neighborhood of 160 GPU's (give or take depending on model). Given the four miners together, we're looking at nearly 1000 GPUs, which kind of defies belief.

I know there is talk that some Scrypt ASICs are able to run the current N-Factor for Vertcoin, could this be an ASIC churning out these numbers? I mean, I know there are GPU farms out there, but this would be absurd.

Is it already time to do the Anti-ASIC hardfork that the devs have promised?
