Gtx 770 2gb vs gtx 760 4gb

So I am doing a little upgrade on my PC I run multi-monitor with a 550 TI
just wondering would I be better getting a GTX 770 2GB or a GTX 760 4GB
 

You game on three screens? Either way, I would choose the 770. 2GB is quite a lot of Vram for most uses. The higher performing card should always be the main consideration.

This. You will not really benefit from the additional VRAM on the 760, so a 770 will simply perform better. If they are similar in price then the choice should be obvious.
