You can go 3 way crossfire BUT your setup is going to run in a (1 x8,2 x4) and bottleneck.
You need a minimum of x8 to have a minimal bottleneck from X16 (1-3%).
So we would have 1 card in x8 mode (very minimal bottlneck) and 2 cards in x4 mode (which will hamper the performance of the cards by quite a big amount)

I'm currently looking for the chart on Tom's hardware about it.
