Can anyone answer me with simple layman terms ,will 4gb HBM will be enough for 4k gaming or game that uses a lot of vram like gta v without stuttering/performance hit ?
4GB is enough for 4K gaming. Stuttering in this case basically after effect when VRAM maxed out. If we use GTA V as an example, I have never max out the settings including the advanced graphics setting but based on the info I found & assuming fury can max out GTA V, 4GB may not enough. Higher resolution also consume VRAM, so need to take that into account too. You can always turn down graphics settings to lower VRAM usage. Basically you can game at 4K with 4GB card.

You are too forgiving and accepting. It's
NATURAL to question all the hyperbole and marketing claims on these slides. Of course two is better than one. The point of he matter is that it took them TWO Fijis to claim that, instead of one. What's stopping them from putting on that same slide that claim of "world's fastest single GPU" right next to the Fury X, instead of putting that "world's fastest graphics card" on the dual Fiji instead?
CFX implementation on anything AMD is still poor so even if it does claim the world's fastest graphics card, having to deal with CFX peculiarities like micro stuttering and missing CFX profiles alone does not ensure "the best 4K experience" as what they claimed. It's like having the fastest Ferrari car around but giving it to drive to an 18 year old who just pass his driving license test. Single GPU card is still the metric to look for to avoid CFX complications.

You can be defensive about folks questioning AMD all you want, but it doesn't help their cause when they're not being true to their own claims. Or in this case, side skirting around vague claims and statements.
Personally to me, THIS was the only good thing that came out of the presentation yesterday:
» Click to show Spoiler - click again to hide... «
It shows forward thinking and innovation on behalf of AMD to think outside the box on what their HBM implementation has done to shrink the PC form factor into a form which was not possible before. Almost like a PC version of that dustbin-looking Mac Pro.
I don't know about the rules but usually most powerful card will be crown to single gpu card.
CFX performance is very good nowadays. No more micro stutters. It's old news. Nowadays the problem is whether the games support CFX or not. That's all. Usually AMD will release driver update to support CFX for certain games. Only problem it may take time.
