It would get pretty close... But AC4 has a lot of advanced graphical features like HBAO+ and PCSS shadows, MSAA, PhysX...etc. Plus it is better optimized for Nvidia cards. So if this game is your main concern. You may want to consider the 750 Ti 2GB.. But either way you will end up having to turn some things down a little. My GTX 780 has no problem with it. But a friend of mine with a HD 7950.. Basically a (R9 280) has to turn MSAA down to 2x and PhysX off.
