Motherboard Features
AMD’s multi-monitor advantage comes from the way it separates PCIe and GPU functions to deliver sixteen PCIe 2.0 lanes to graphics cards (up to two) without sacrificing integrated graphics functionality. Its Catalyst driver package controls both onboard and discrete Radeon graphics controllers simultaneously, seamlessly managing multiple desktop configurations. The three boards in today’s roundup have another advantage over those of our recent H55 comparison, in that those products didn’t support DVI dual-link mode for extra-large displays.

Unfortunately, while Gigabyte’s dual-link mode appeared to accommodate our lab's 2560x1600 display, loading the driver seemed to break this feature. This is most likely a driver bug, since AMD’s Catalyst 10.3 Preview package is not yet finished.
Another advantage today’s motherboards have over the Intel H55-based competition is the chipset’s additional PCIe 2.0 lanes, one of which supplies each of today’s motherboards with the same USB 3.0 controller at its full 5.0 Gb/s interface bandwidth. Intel’s chipset lanes run at half-speed, so that two lanes and a costly PCIe switch are required to reach the controller’s maximum throughput.

Doesnt seem worth it to me!
OK i cant make up my mind if the 6 Core Phenom II will give a better performance boost to make it worth while getting a 890GX.
This also begs the question if other chipsets will get bios updates to accept 6 core Phenom II such as 790GX/FX - 780a/980a etc...
It's possibly down to manufacturers choosing whether to update BIOS for it, and if the power regulation's up to it.
Mr. Soderstrom (or anyone else):
I'm trying to decide between these 3 boards, and the Read/Write performance benchmarks so heavily favor the ASUS that I'd be foolish not to pick it. Do you really think the difference is only due to BIOS upgrades, or is there a fundamental difference between them when it comes to storage interface? Any advice would be much appreciated. Thanks.
