Long story short
I have an lan party coming up so i need a new graphics card
Will be playing aaa titles at 1080p high/ultra
So i am deciding between two cards
Msi rx 580 8gb gaming x
Or
Sapphire rx 580 4gb nitro+
So the msi one i should wait a long time and risk it not arriving before the lan
The sapphire one should arrive in 7-10 days if oreder now
So i dont want to risk but i would like to get the futureproofness that the 8gb of vram brings
Amd the prices are the same too
Which one to get???

It is not useful to pick a graphics card based on specs.

VRAM has become a marketing issue.
My understanding is that vram is more of a performance issue than a functional issue.
A game needs to have most of the data in vram that it uses most of the time.
Somewhat like real ram.
If a game needs something not in vram, it needs to get it across the pcie boundary
hopefully from real ram and hopefully not from a hard drive.
It is not informative to know to what level the available vram is filled.
Possibly much of what is there is not needed.
What is not known is the rate of vram exchange.
Vram is managed by the Graphics card driver, and by the game. There may be differences in effectiveness between amd and nvidia cards.
And differences...

oh okay, well,
since it comes to this,
its your choice now to pick between those two,
while I still prefer the futureproof
you might need the 4gb sapphire to be able to play at the lan party

How is that even the best answer? It's no different than OPs question.

See if you can borrow a more up to date spare GPU from one of your buddies for the lan party just in case your prefered 8gb 560 doesn't arrive in time.

And differences between games.
Here is an older performance test comparing 2gb with 4gb vram.
http://www.pugetsystems.com/labs/articles/Video-Card-Performance-2GB-vs-4GB-Memory-154/
Spoiler... not a significant difference.
A more current set of tests shows the same results:
http://www.techspot.com/review/1114-vram-comparison-test/page5.html

And... no game maker wants to limit their market by
requiring huge amounts of vram. The vram you see will be appropriate to the particular card.
