A coin made especially to run better on nvidia cards? Meh, i think a coin should be made with security in mind, not videocard brand.
Protoshares was not designed to run better on nvidia cards or gpu's in general. The algorithm was designed to be gpu and asic resistant and currently GPU's are only 1.5-2.5x faster compared to good CPU's. This is a plus however the big selling point of protoshares is that they will provide you with BitShares and any other DAC released by Invictus. BitShares are 100% proof of stake and finally something besides "another coin."
*edit *The article is also incorrect and both nvidia and amd cards can mine the momentum algorithm.
