Anytime you want better graphics, it needs more memory on the GPU card to do it, so 6GB would be twice as much 'space' to do things your asking than 3GB. So yes it does help and is worth it for more than GTA.

Tom and parani are right You should buy the 6GB version everytime you increase the graphicall settings you use more Vram and many games to be played in the highest settings possible require minimum 3GB nowdays so it's better to grab a 6 GB and have nothing to worry about in the future
