Best AM3+ mobo?

so today i finally decided that i would stick with upgrading my current rig rather than doing quite a bit more and switch over to intel (just getting mobo rather then mobo and cpu). currently the mobo would run

8gb of 1333 ram

radeon 6850

fx 6100

 

 i would like it to have/be:

compatable with 8350 and future chipset

crossfire is a plus but not majorly needed

quite a few sata 6 gb/s ports (at least 6 please)

under $160 USD if its good i may splurge an extra 20 or 40 bucks

be able to handle basic raid setups (4 drives in raid 0, etc)

at least one pcie 2.0 or higher port

some other expansion port for sound cards and such

decent at overclocking

 

thanks for any advice

 

ps

i also at this time i plan to upgrade from windows 7 home to windows 7 pro (or windows 8 havent decided yet)

 

some mobos i have been looking at :

I've got the Gigabyte 990 UD5 for my FX8350, both of the boards you've chosen are pretty much top of the line as far as consumer friendly boards are concerned, AMD boards aren't really ever that epensive.

The Asus Sabertooth 990FX Revision 2.0 is probably the best AM3+ motherboard though.
