So - maybe I am stupid - but what then is SLI for ?
Concerning the power question, I got the quote from my seller, that for a 580 I need a stronger power input, with the 590 i dont ??? (We are basically upgrading a "gamer PC" tht they are offering)
I still have the chance to change things tomorrow, so your Input is very appreciated ....

590 has 2
Fermi 110 chips while 580 has one. On 590 they run on lower frequencies than on 580. Now, from lowest to highest power requirement this translates into: 580 < 590 < 2 x 580.
Thus your seller is either uninformed or there was some kind of misunderstanding. I am willing to bet that he meant you can run 590 with the current PSU, but not 2 x 580's.
Ditch that 590 and go for a GTX 580. If you really want an SLI solution, get another later on or now if the budget allows it (preferably in a combo with a MBO equipped with nf200 chip on it so you can run them both in x16/x16 bandwidth).
In all above solutions you will have 1.5 GB of VRAM at your disposal.
