OK, I have a GTX 660, and i'm looking to upgrade to a budget GPU, I have been looking at the 750ti, 950, and the 1050 if the rumours are true, I did some comparing on GPUBoss, and my 660 seems to be almost equal to the 750ti and the 950, I think this strange seeing as the 660 was released mid-late 2012, and the 950 was released mid 2015. Will i notice a difference if I upgrade to the GTX 950?
