Can you do 4-way crossfire with AMD RADEON RX580?

[snatchysquid]

and do you need a crossfire bridge for that?
thx for the help

msi AMD RADEON RX580 OC - 8GB GDDR5, asus AMD RADEON RX580 Top OC, gigabye AMD RX580 8GB XTR: these GPU's for example

yes. but amd have just stopped crossfire support. instead they are calling it multigpu support and it may only support 2 gpu's (confirmation needed).
seemingly they are stopping driver development on more than 2 cards and will leave it up to the devs if they want to implement 3+ card compatibility.

why would you want 4x580's the scaling falls off dramatically 1s you go over 2...
1=100%
2=150-180%
3=180-210%
4=185-215%
thats an awful lot of money to throw after 35% or less performance from the extra 2 cards.
