I dunno, I like the idea of RTX in some ways, I like anything that is designed to take the market forward in one way or another but really RTX isn't "RTX" is it, It has always felt to me like NV's way of claiming a technology that's been around for a decade or more. RTX is simply NV's implementation of DXR as it is in the DirectX 12 API, aside from de-noising etc it's really nothing that groundbreaking. To me DLSS is actually a more impressive tech but sadly I think that still needs quite a lot of work as well. The NV marketing machine knows exactly what they are doing though and it's impressive from that perspective and also the perspective of that marketing bringing ray tracing more into the mainstream.
From my perspective and with what I do for work and play, AMD just makes more sense for my requirements at this time, or at least it does with the compute focus side of Vega and good/ constantly improving support in Linux since AMD drivers are open source. My 16gb vram buffer plus pro driver support on Radeon7 for some things makes it almost my perfect card at this point in time, mainly due to the fact I can't rightly justify the cost of a equivalent instinct product to be honest. The fact that I can then boot it into windows and frag noobs until my heart is content at 1440p and slower games @4k makes me very happy indeed. The trade off then, and the question I ask myself is would I trade the above for a card where my gaming performance is as good as it could be but where I take bigger hits in my more compute heavy workloads, or in fact where I have to mess around a lot more to make it work in something I'm not massively familiar with? I don't know if there is a right or wrong answer but for me I have fun with my mates gaming and don't feel like im missing out on anything in particular hence the radeon 7, for others where they have a gaming or cuda focus then there may well be a very different answer
That's why Navi to me fells odd, it's akin to going for a more NV product and losing out on some of the reasons I am using what I am using
