If you're even considering the ASRock 990FX, then I would recommend as a comparison Gigabyte's GA990FX-UD3 instead of the 970A-UD3: it's still cheaper than the ASRock, has a better reputation, & has all of the 970's features plus eSATA ports, & faster slots (2 x16 and 2 x4 PCIe slots, 2 x1 slots, & 1 PCI).
