Gigabyte’s GA-890GPA-UD3H is based on the AMD 890GX+SB850 chipset. This new chipset features support for future 6 core CPU from AMD (Thuban) and now supports the native 6Gbps (SATA3) interface for HDD/SSD in RAID 0,1,5,10. It also has an integrated ATi Radeon HD 4290 (DX10.1) graphics with 128M sideport memory support. Just like its predecessor 790GX, it supports ATI CrossFireX, Hybrid Graphics.
Gigabyte’s GA-890GPA-UD3H features on its branding of “333” – USB 3, Power 3X and SATA 3.0. As we all know, Gigabyte started the trend of embedding the NEC USB 3.0 chip on its P55 and H55 board last year. It had since released new models for both platforms. With the new AMD 890GX which offers better bandwidth, you can now get true USB 3.0 performance as the NEC USB 3.0 controller is now connected with 5Gb/s using native PCIe x1 2.0 from the AMD 890GX chipset.
On top of that, Gigabyte GA-890GPA-UD3H comes with Ultra Durable3 that is 2oz copper PCB, 50,000 hrs Japanese solid caps and Dual BIOS. It incorporated a 4+1 power phase design for maximum stability. For the energy conscious, it has an Easy Energy Saver feature too. It is EuP Ready as well.

So far not so good. I upgraded my system that still had some old IDE DVD drives and it took me hours to troubleshoot my audio problems. It seems if you use the on-board GSata/IDE controller it has conflicts with the audio and Gigabyte has no solution.
So you can choose clean audio or IDE devices …
