this motherboard can handle a CrossfireX?

If ya grab that MoBo or the Asus equivalent which THG liked for its OC ability, get the combo and save $20

Both will do CF but only at x8 x8 .... read this to see if that matters to you

You'll want a NF200 chip on there if ya want x16 x16 ... the two most popular boards for x16 x16 are the Asus WS Revolution ($260) and Gigabyte UD7 ($320). You can compare the two here.
