You are limited by the lower RAM amount, so you will have dual 480's but only 4gb of VRAM.

It doesn't stack in DX 12 either, nor vulkan. Only in DX12 multi-gpu of which there is only 1 game. and multi-gpu is NOT crossfire.
I've just realised something which I think forces me to buy 1070,
My PSU is 650w, a good 80 plus gold one, but still 650w. I also have an i7 6700k, with that being overclocked I hardly can imagine 650w being enough. What do you think about that?

A single card is always better than two. While in raw power 2 RX 480's may be faster, not every game supports crossfire, and crossfire sometimes has micro stutter issues. I would get a 1070 over buying 2 RX 480's.

same here i'm running a 6700k setup with a 1070 and much prefer it over my r9 290Xs in Xfire that I used to have. Performs a lot better at 1440p too due to the additional VRAM. System runs a lot cooler for it too in all honesty. So yes, I would far more recommend the 1070. both in terms of performance and power consumption 
The problem is my budget. I currently can afford something around 350 euros and later I can add on top of that. Right now, I can only use my hd graphics 530 (from i7) which sucks a lot.
And I'm guessing newer games must have crossfire support, if not, single 480 should handle 50+ fps in 1080p (that will later be 1440p).
So, I'm still not sure if 650w is enough. Otherwise I'll just keep playing dark souls over and over again until I can get 200 more euros.

if you are able to hold out. wait and save for the 1070. if not get the 480 but make sure you go for the 8gb version as running at ultra settings at 1440p on shadow of mordor (my main game atm) its using about 7gb of the 8gb total VRAM. @Rouge Leader may be able to shed more light on this than I can but that would certainly be my preference anyway

The RX 480 is more than enough for high fps at 1080p. I have one and its great. So you don't need to worry so much about adding a second. As for running 2 actually a good 650w psu should do it:

If you have a good 650w PSU youre fine.

Yes, the 6700k is still only a 91w cpu. It will draw more but not enough to overdraw that PSU (unless you go crazy with liquid cooling and super high numbers).
