I am very close to buying a 2560x1440 monitor (or, perhaps even the now affordable 4k Samsung U28D590D) and am looking at a new graphics card as I feel my 2GB 7850 might not be up to the task for modern gaming. Looking at the GTX 760 and 770 I notice there are 2GB and 4GB variants, £165/$277 for the 760 2GB, £205/$344 it's 4GB brother, and £220/$369 for the 2GB 770, £290/$487 for the 770 4GB. As I am going to be gaming in greater than 1080p, is it worth the extra money for the 4GB versions? I hear that in some cases it is simply not worth it.

If I decide to go with WQHD I will probably go 760, and 770 if I go 4k.

As a side note, does anyone here game on 4k, and if so what card are they running?

Thanks!
