I think the 660 Ti is about 760 level, which is about 950 level, which is about 1050 level. So you'd be moving up from a 1050 to a 1050 Ti roughly speaking. Frankly, unless you have a more specific bit of information, such as a game that you need more performance on, it's not clear if this is a worthwhile upgrade. The fact you even mention waiting makes me think you don't NEED an upgrade right now, so why do it?
Ah, thanks. I just wanted to play ARK Survival Evolved at a much better framerate cause the optimization on that game is bull. Thanks for clearing that up for me, haha!
