I have read this too but I'm a little skeptical and don't want to spend the money and find that it is limited.
Is there reason for me to be skeptical?
I run a Fury Tri-x and a 1080p monitor,
You'll find the odd title that requires a setting such as textures to be turned down one but as I highlighted with screenshots of ROTTR it makes a negligible difference to image quality, That particular game I believe was purposely pushed past the 4gb limit of many cards but that's a different discussion.
While the compression used for Fiji appears to be better than what was used on older cards it's not really any better than Nvidia's so don't believe it is. At the end of the day 4gb's is 4gb's not more because it's HBM.
As for the Fury at 1080p, I max 90% of every game and it is fine, I do that running the games at 1440p via vsr and get respectable frame rates that are perfectly playable.
As an example DOOM running at 1440p via vsr sits well above 150 most the time sometimes hitting as high as 190/200,
Dying light sits in the 70's or 80's most the time,
When I bought my Fury one year ago it was a toss up between it and a 980ti, Today I can honestly say I'm happy with the choice I made, It's been a great card and it continues to do a great job and I'm confident it will continue to for some time..
Having said all that if was asked would I buy a 4gb card today the answer would be No, However if I was asked would I buy a secondhand 980ti today the answer would also be No. Of the two I'd buy the Fury because it's new and I have more confidence in it going forward, however I'd be more inclined to save up a bit more and buy the cheapest non reference 1070.
