Fair enough, pay more and get more (most of the time). I can't argue it's nice to have the option to throw money at something if you can afford it. However, the "amount of more" is what I take issue with. It's still a poor value and essentially a ripoff in comparison to Freesync which can give you a very similar experience for far less money. You can ignore the $300+ price premium all you want (it's sometimes larger on the higher end monitors, which is normally the same audience who buy 1080 Ti's) but you can get an awesome gaming experience (possibly superior, depending on the type of Freesync panel like the Samsung UWS I mentioned earlier) with a tuned Vega 56 + 1440P IPS/VA panel. 4K gaming is still iffy on a 1080 Ti without reducing some features, but that's not a huge deal as you can always turn down a few superfluous things like 8XMSAA to get the FPS back up, but then you're back to gaming on a 60Hz display....
The ideal gaming setup today includes at least a 27" 1440P IPS 144Hz, or more recently 100Hz 34"+ UWS 1440P monitors. Compare the prices between Freesync/Gsync here as that's what high-end gamers will be targeting for purchase. Now take a Vega 56, flash it to a 64 and undervolt it to sane power levels and enjoy ~1080'ish performance with the choice of a much larger list of less expensive Freesync monitors.
If you waited a year for Vega and got pissed because it failed to live up to certain expectations it doesn't invalidate the card as a decent option for people who already own a good Freesync display, or for gamers who want a high-end monitor without paying a $300+ premium.
Yes, Elfear is correct in that if Nvidia would just adopt the open standard we gamers could choose whatever videocard offers the best value. Hopefully, this will happen but I'm not holding my breath.
Anyways, I feel like I'm repeating myself so I'll stop here.
