MSI K9A2 Platinum review
 

There are not a whole lot of motherboards using the 790FX chipset at the
moment, and if we remove the ones equipped with 4 PCI-Express slots which
give you the Quad CrossFire opportunity, there are probably only a couple
boards out there. Actually I tried searching for reviews of this
motherboard, but only came up with a couple news flashes about MSIs release
of the motherboard. The reason for this might be the limited spread of AMDs
new Phenom processor with 4 cores. Something the motherboard manufactures
isn't too happy about.
