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

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 2013 , 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. System Specs: CPU: AMD FX 6300 3.5 GHz @4.1 GHz (Turboboost) RAM: 8GB Corsair 1600MHz DDR3 (2 x 4GB) PSU: CoolerMaster GX650 650W Power Supply OS: Windows 8.1 Pro Both cards tested were the standard Geforce ones at stock speeds. Thanks for watching :)
