Gtx 770 2gb or 4gb?

I'm going to buy a gigabyte gtx 770.  I play games but i also do a lot of video editing.  I use adobe premier and after effects mostly.  Will i get a benefit from the 4gb card over the 2gb card?  I don't mind spending the extra money for the 4gb, but i would like to spend it on something else if there's not much performance gain.


Go the 2gb, because unless you are running stuff at like 5760×1080 or rendering 4k material then most of that 4gb will be going to waste.

What program are you using btw?
