Best QuadFire supported AM3+ board?

[rabidz7]

Price is not a concern. What is the best QuadFire board for use with a 9590?

Personally, I am currently using the GA-990FXA-UD3 and M5A99FX with 5 card mining rigs and both handle that amount of cards with no issues.

OP, do you mean Quad or 4-way CrossfireX; in other words, two dual-gpu cards, or 4 individual GPUs? Because I don't even know of any boards that can support 4-way that aren't Intel. For example, all the boards atp listed above (and any board with at least two PCI-e x16 slots) only support Quad-CFX by using two dual-GPU cards, but none of them support 4-way as they only have 3 PCI-e slots for a 3-way setup at best.

I mean four separate graphics cards.
