Yes. You are looking at either high or medium at 1080p depending on the game. I3 and 750ti are a good budget combo. 300 w is Nvidia requirements for the card, so it should be enough.
Okay Thanks Dude. My mate said i can have the cpu in his old pc its a i5 2320 is it worth changing it for my i3? And will the Psu still be able to handle it?
