MSI shows K9A2 Platinum (AMD RD790) mobo
 

You will notice that the rollercoaster type heat pipe which we saw on MSI P35 boards has gone and been replaced with a more placid looking design which cools the PWM area, Northbridge and Southbridge via its copper material. There are a total of four PEG slots and when all are in use, they are at x8 but when only two are in use they run at x16 each.

We asked the need for so many PEG x16 slots and asked if it had anything to do with Quad Crossfire and were told that we will see three-way Crossfire first and Quad version later (we would assume next year). There are a total of six SATA 2.0 slots (four onboard and two eSATA on the I/O panel) from the SB600 Southbridge and an extra two are added through a Promise add-on controller (they are colored blue).
