AMDZone have a review of the A8R-MVP Crossfire motherboard from ASUS:
So we have seen for the first time what Asus has done with the Xpress 200 CrossFire chipset. As we have noted it has not gotten the same treatment as the A8N32-SLI Deluxe as many accessories, features, and software are not included here. The BIOS work though is quite similar. Again we are glad to see Asus go with the M1575 chipset despite it delaying the release somewhat. Asus has a solid offering with the A8R-MVP, and certainly any attention from them must be good for ATI on the chipset front. Asus fans partial to ATI have a good board to chose from, but those looking for a top overclocking experience may opt for the DFI board instead.
