A10 Graphics Configuration:

I currently have an ASUS A88X Pro Motherboard with a pair of Radeon R9 270's. They are powering 3 HP 19" monitors in Eyefinity 4320x900 resolution.

 

I also have a 32" TV which is operating off the R7 240 integrated to my A10 7850k.

QUESTION: Is it possible to drop a R7 240 into the PCIE 2.0 16x @4x slot and Crossfire those two independently of the Eyefinity rig?
