If you're planning on playing a lot of Ubisoft games now or in the future, go with an nVidia gtx 760 or 770.
If you're playing anything else, a gtx 280/280x would be pretty good.
I play whatever I happen to have, mostly older Steam games, not a lot of specific Ubisoft games though. So really looking for something that is overall good for anything, not bound to a particular company. Mostly the Arkham games I am going through right now.
The Arkham games are focused on Nvidia cards like the GTX 760, due to the PhysX mostly.
How it works out is:
AMD has higher performance per dollar in most games. For example, the R9 270X is normally around $180, and it performs about as well a $230 Nvidia card like the 760 in games that don't use Nvidia effects.
Nvidia supports more proprietary technologies that allow them to be compatible with any game's effects, though with lower performance per dollar in many games.
The upside to AMD is that if you don't play certain games they're an overall improvement at the same price point. The downside is AMD card performance drops hard in certain games, and they don't always support some of the effects needed for real "ultra" settings in certain games.
Nvidia cards tend to run cooler and use less power than AMD cards, but that's not a big concern for most people unless they have bad power supplies, or are trying to build a PC with a low environmental footprint.
