I have read that adding gpu's in sli don't exactly give you more vram but just better performance in terms of rendering and frame rate.
But as amd GPUs are quite flexible, combine with most of their own cards regardless the manufacturer or model, will having it in crossfire increase its performance of VRAM or will i just get a slightly better performance on average.

VRAM doesn't stack, simple as that.

As far as performance goes, that's entirely dependent on how well a game supports multi-GPU setups, assuming it does at all. As a result, the performance increase (again, assuming there is one) can be all over the place. You're entirely at the mercy of the game developer and if they won't implement Crossfire, then you're stuck.

The rule of thumb used to be that you'd buy the single best GPU you could afford and then buy another one when performance dropped below what you'd like. These days, it's better to buy the single best GPU you can afford and then sell it to fund an upgrade to something better.

Crossfire uses vram from only one card but processing power of two cards. In crossfire enabled dx12 games many report 85% or more increase in game performance. Vram use in these crossfire games is usually below 5 GB anyway.

AMD is still working on the dx12 multi gpu feature which would replace crossfire and allow vram and gpus to be fully utilized on both cards.
