Nvidia Geforce GTX 750 Ti 2GB vs GTX 750 1GB - Does Ti make a difference?

This is a comparison beween the Nvidia Geforce GTX 750 Ti and the standard GTX 750. I tested two games which were Assassins Creed 4 Black Flag and Tomb Raider new , one of which is terribly optimised and the other not. The difference is not too big and both cards should be considered worthy candidates for a budget next gen PC build.\r
