Their will be major fps increase so you be able to get 60fps ULTRA on 95% of most games and all games at 1080P.
However, you might get issues with latency as crossfire isn't that great at low latency.
How well it will perform on Watch Dogs and Titanfall at Max quality?
In general it should get 60fps since that is basically a r9 290 with both cards.
However this will really depend on your CPU, if you have a budget cpu like a Athlon x4 760K or a FX 4350 then your never going to get 60fps.
EDIT: Never mind, didn't see you posted your specs. It will be fine then since a i7 is plent of performance, and you should get at least 60fps.
