Cheap Crossfire and DDR3 motherboard???

Hey guys, so i built a computer back in august of last year, but i got a cheap ass motherboard and im regretting it dearly now.

So i was wondering whats the least expensive motherboard, that has 4 DDR3 slots (im thinking about getting a lot of RAM in the future) at least 2 PCI-e X16 slots that are Crossfire enabled, and supports Socket 775 CPU's? If a slightly more expensive motherboard gives much more bang for the buck, then feel free to list that in here to, as i may spend a little extra cash if it has a nice bit more features. If possible i'd also like to have a motherboard that supports 1333 FSB and above, but it needs at least 1066

If you need them:
Q6600 intel Quad @ 3.0 GHZ
4 GB DDR2 RAM (i am going to purchase a pair of DDR3 sticks for the new motherboard)
160 and 250 GB hard drive
ATI HD 4890 Graphics card
850 Watt, with 60 amps on its 12v rail


Thanks in advance for all your help!
