watch_dogs with nvidia cards - what next?

What game is there to offer though? There won't be anything really that good out till the end of the year.

sell the game for a $1 = Profit

Wait a year, they'll probably will add new Batman in 2015.

The Crew- releasing 11.11.14

You could sell it and spend the money at your choice :)

Maybe.
I wouldnt buy a graphics card because of the game it adds as a bonus though

Ubisoft is quickly becoming the next EA.

They probably offer Batman: Arkham Knight like they did with arkham city and origins.

GTA V

Usually games are at least optimized well enough for both brands, AMD also has games like this, thing is Watch Dog fails on both and Ubisoft knows this...
