Question was just if it's possible there would be a coin in which nvidia can have the advantage. I'm sure there are lots of people in similar position that would be happy with this.

Hashcash based coins? no
Coins based on some other proof-of-work? maybe

It wouldn't be possible to create something that can only be mined on NVIDIA hardware, but there could be some computational problems where NVIDIA hardware might have an advantage in (at least initially).

So, to answer your question, it *might* be possible.

The problem is, I don't think anyone putting in enough work to design such a coin (based on a different proof-of-work) would care about something like this. It really doesn't do anything to secure/decentralize the network. True, it might work at first since there are not any mining farms based on NVIDIA, but there are plenty of render/compute farms based on high end NVIDIA hardware (Tesla), so it wouldn't be something that would be advantageous to laptop/single-GPU users in the long run. Personally, I think it's often forgotten that crypto-currencies are not designed for miners, and mining just provides an incentive to expend the electricity needed to decentralize the system.
