Conclusion:
ASRock's quality continues to improve as well as feature set. Overall we recommend the ASRock AM3790GXH/128M as a great Socket AM3 motherboard and the path to go if you're building a new system. We're still not sure why the boards contain toggle switches at this point for Crossfire, however, if you're changing your video card setup a lot between those then that won't be for you but most will only change that once or twice in a board's lifetime. Most of all we're happy to see BIOS improvements in the ASRock board to be fully featured for overclocking the board came back from a bad overclock a number of times.

Pricing:

You can pick up the board for $129 which is a good price for triple PCI-E 16x slots and a newer type of motherboard.  The AM2+ 790GX ASRock board is a little cheaper at $109.
