Help me choose a motherboard/graphics card?

[adamj]

Hey, I'm looking to pick out a motherboard for my OS X rig. I want to find one that is compatible with the following and will work well in OS X.

 

My needs:

-Raid 1+0 (4 1TB SATA II)

-2 SSD's (128GB each)

-1 Blu Ray drive

-Fan controller on front of case

-Socket 1156 for a quad core i7

-2 PCI-E graphics cards (option for a 3rd would be nice)

-Built-in Wireless N or slot for a wireless card

-Power connector at bottom of motherboard would also be nice

 

I'm also looking at getting a graphics card to drive my 3 1080P monitors. I'm currently looking at buying a pair of 6850's but if OS X supports driving 3 off one card then I'd just get 1. I wouldn't plan on going crossfire as I've heard it's incompatible.

 

Also, would a 5770 be better? It's a bit slower but I know they use them in the Mac Pro so I figured it might be more compatible.

 

 

One last question, is it possible to partition a 1+0 Raid array? I'd like to use 1TB for windows and 1TB for OS X.
