OCIA.net has posted their review of the MSI 890GXM-G65 AMD Motherboard.

Although AMD's latest chipset the 890GX, codename RS880D, is very similar to last year's 785G - RS880, the most striking improvement is the addition of a new southbridge, the SB850. Supporting USB 3.0 and SATA 3.0, the SB850 opens up much needed additional bandwidth for faster external accessories and solid state drives. While many 890GX boards utilize a full size ATX format, MSI's initial offering is the 890GXM-G65, a microATX style. The 890GX offers integrated graphics, using the RV620 graphics core, which supports DirectX 10.1, Shader Model 4.1 and a host of video decoding and acceleration formats. CrossFire is supported but the 16 available lanes must be split into a dual 8X configuration. Hybrid CrossFire is also available, allowing use of a HD5450 discrete video card to be paired with the onboard for up to a 25% improvement in gaming performance.
