The upcoming RD790 motherboard from Gigabyte is GA-M790-DQ6. But, causes it is not production yet, so some changes might still happen. The disappointing change is, Gigabyte had decided to remove FireWire 800 support from this AMD motherboard. On the rear panel, Gigabyte also removes the parallel port and it is replaced by two mounted eSATA ports. But, If you still need this parallel port, don't worry, Gigabyte still has added an internal connector for it and supplies one with a long cable in the box with the motherboard.
The heatpipe cooling system has been changed to be a better version with two instead of one heatpipes and some other modifications. Not only that, Gigabyte puts the power regulation on the motherboard all in a stright line which it easier to produce an efficient cooling solution. Finally, the GA-M790-DQ6 features AMD RD790 chipset and it supports HyperTransport 3.0 and AM2+ CPU’s.
