Gigabyte has no intention of being caught short handed once AMD's Bulldozer platform rolls into town. Getting a jump on the new CPUs, Gigabyte just added three more AM3+ boards to its lineup, all of which sport AMD's AM3+ socket. These include the rather plain-named GA-990FXA-UD3, GA-990FXA-D3, and GA-990XA-UD3.
That brings the total number of 990FX boards in Gigabyte's stable to five, and you can bet there will be more. Gigabyte's M.O. is to release several boards for any given chipset, followed by second and sometimes third revisions of any particular model. It gets a little dizzying and isn't always easy to tell what separates board A from boards B and C.
In this case, all three support AM3 and AM3+, come with the SB950 southbridge, sport four DDR3-2000 memory slots, SLI and CrossFire support, GbE, 7.1 channel audio, six SATA 6Gbps ports, and Gigabyte's DualBIOS technology. The GA-990FXA-D3 has three USB 3.0 ports, while the other two models have four. In addition, GA-990FXA-UD3 and GA-990XA-UD3 boast an "Ultra Durable 3" design and include two eSATA 6Gpbs ports.
