shall i go for 3 way crossfire?
does 8x/8x/4x or 16x/8x etc make a difference in gaming?
will i need to upgrade my psu as well if i wanna put a 3rd card
suppose i stick with 2 cards, is this motherboard suitable for 2 cards? if 3rd card then which mobo min i require?
will i gain any performance benefit if i put another 2sticks of 4gb each?

Theoretically having a 3x crossfire should triple your performance of your single gpu, but that's never the case because of lots of reasons, which I won't explain here.
Your crossfire 280x should be able to play all recent games maxed out at 1080p.
If you must upgrade then get more ram, it'll help in rendering, and probably an ssd, but having and extra gpu is not going to make a significant change unless you are looking for 4k gaming.

Ps :If you have your mind set on getting an extra gpu, then try Asus or asrock mobo which supports 3x crossfire. And you might need a 1200 watt psu for having some extra overhead.

another ssd?

If you have a 256gb, then you are good to go
