Thanks you for your time...

For one 1080p screen, 2GB is OK.

2gbs are enough for one screen monitor, if you play higher resolution with 2 or more monitors 4gbs will be required

Anything that is going to cramp 2GB on a 760 would hit a GPU limit long before a memory limit.

For one 1080p you should choose the 2gb version only
