Nice graphics, thanks for going to all that trouble
So the quick stand out is that there's a big difference between the GTX 980 and the GTX 980TI, but yes I see what you mean the GTX 1060 is indeed out performing the GTX 980, although I'm totally behind in terms of not having done any research for the last few months I was aware of the the "predicted" performance of the next gen Nvidia, it seems that all the publicity and performance predictions were in fact accurate, especially the power consumption differences which are quite stunning
It seems if your buying new you should perhaps go for the new nvidia but with cpu's perhaps not so important except for the point you made about mobo's which seem to be more of the limiting factor
Thanks again for the update, really interesting, I'm quite interested in legacy performance of hardware and the limitations of that and how "necessary" it really is to have the latest and greatest in terms of being able to enjoy good quality game play especially when factoring in the cost of new hardware, it's particularly interesting because this subject can translate into saving quite a few bucks/pounds for the typical user
