It is weird but it works. I'm not underestimating my 660 TI, I think it's a great card that performs well. It has some great performance features. I'm talking about a 1050 TI not a 1060 too.
It just, for some reason on my CPU, performs better with a card dedicated to physx. I tested several cards, a 1050 ti alone with with my 660 TI, etc, and they performed pretty equally.
I didn't say 1060 at all o_o. I just found it interesting that alone, the 1050 TI or combined with another GPU, seemed to perform about the same as my 660 TI and 750 TI SC and yes I know my 660 TI is a very strong card.
