My money is going to the whoever offers the best perf/$ at their top end between team red or team green. Both brands will likely release cards that will be capable of 4k 120Hz for at least a year and that's enough for me.
To be quite clear amd hasn't competed on the high end for a long while and offering comperable performance to you competitors best card from 2 years ago doesn't count as competing on the high end.
if it comes down to you picking one this way just understand you're not shopping for a high end card your shopping for a upper mid tier at best. And if performance is where it supposedly is for both amd and Nvidia then amds best will be more in line with the xx70 series card which is in the bottom half of their new cards with just 1 level below and 3 above.
if you're expecting amd to have a gpu good for 4k/120 you're sadly mistaken their best will roughly be on par with Nvidias best from 2 years ago. as an owner of said card I can tell you if was barley a "4k/60" card let alone /120 and without something like DLSS 2.0 there no way this level of hardware gets near your goal.
To be clear neither in the ballpark you're planning to shop will have a true 4k/120 card but the Nvidia one will have the benefit of DLSS 2.0 (whose adoption is just growing and growing) and without it the amd cards will never deliver even close to the performance you're looking for.
At the end of the day if you want thrbbrdt performance there's no other option than Nvidia high end xx90, titan and only those cards will actually be close to 4k/120 (as in true though I fully suspect they'll blow past it with DLSS 2.0).
thr price to power and features ratio will more than likely go to the xx80 class as a $800 card that gets you 90% of a $1400 one all while giving you 20% more than amd's best with features amd just can't match (like DLSS 2.0).
Their best card will likely be around $600 and might have close to 2080 ti performance which would be great if Nvidia didn't have an entire new lineup lainchkngn(even before amd gets the 2080 ti "killer" out the door.
BS.
I have "economic power", but would never consider obnoxiously overpriced GPUs (and, to render what? Consoles are going 4k this gen)
Well it just means you're gaming performance isn't a priority for you but to act like an elitist while also speaking like this is basically hypocritical.
Any person with a decent living wage could make this stuff happen if it was their biggest goal but many do not give a crap about anything except pressing buttons and seeing stuff happen on screen. that's fine casuals are very important part of the market,but actual true enthusiast are also important as our need for the cutting edge (and our means to actually obtain it) is what keeps the manufacturers pushing for faster and faster hardware.
the only reason pricing has become as you said "obnoxious" is because of economics and lack of market competition. AMD has failed to compete at the top for almost a decade now amd without them getting their act together Nvidia is left with no option but to continue pushing forward wktht thier only "competition" being the need for people to keep a certain amount of money in their pocket vstthe benefits of the much more powerful hardware.
as performance continues to increase and mew features added Nvidia has no one forcing them to charge less to stay selling and are only fighting with our need for the extra power. Until they price things so high they don't just sell out instantly and consistently they'll have a duty to their shareholders to push things just a bit more until they see a negative impact.
the fact that were getting a xx90 and higher priced categories across the board says they most certainly haven't seen that kind of impact whatsoever.
of you want pricing to be less "obnoxious" maybe give AMD a reminder that being 2nd best isn't good enough.
