Here is what I got:
Kingston 1333 MHz 8 gb
4 casefans
I5 4960 (not overclocked)
Gigabyte 290 oc
Reference 290x (don't know which brand because the person I'm going to buy it from didn't know he just said radeon ...)
3 sata harddisc's all together 3 TB and 7200 rpm
2 ssd 70 gb

My psu is a Cooler Master 750W silent pro. Is it possible to do crossfire with this psu or otherwise does anyone can tell me what happens if it doesn't work and can someone tell me if there is a psu under 100 euro's that can handle this?

I don`t think it`s enough, and don`t buy that card.
The 290 and 290x are different cards, so they will not crossfire well - maybe the 290x will become a 290 (non-x) in the x-fire if you`re really lucky.
Also, the 290x sounds like it`s the reference one, which gets very hot and extremely loud.

So don't buy the 290x? I wanted to put water or CO2 cooling on de 290 and the windforce cooler on the 290x so that i could overclock the 290 to be a 290x

The 290 doesn`t have the CUDA cores and other stuff enabled as an 290x, so there`s no way to make them be the same.
You can get it OC`d to get let`s same close to the same performance, but that doesn`t matter in crossfire.

You need two 290`s, or two 290x`s if you want to X-fire.

Yes, you can do it, but the 290x would become a 290.
So if you can get the 290x extremely cheap, you can go ahead.
If not, just get another 290 non-x and crossfire it with your current card.

Also, the refference 290x as I said gets hot and lows, so crossfire might make it even worse.
