It was only on Friday that Gigabyte revealed its first two AMD 990FX boards on its website and now three more models have made an appearance. This time around we're looking at two more affordable 990FX models and one 990X board, so click on through for a closer look at the three new boards.

It was only on Friday that Gigabyte revealed its first two AMD 990FX boards on its website and now three more models have made an appearance. This time around we're looking at two more affordable 990FX models and one 990X board, so click on through for a closer look at the three new boards.

So starting at the top and working our way down we have the GA-990FXA-UD3 which has a black PCB and looks rather smart for what should be a fairly affordable board in the grand scheme of things. We're looking at a slightly simpler slot layout compared to the 990FXA-UD5 with four x16 PCI Express slots arranged as two  non-switchable x16 slots and two x4 slots. There is also a pair of x1 PCI Express slots and one PCI slot.

The 990FXA-UD3 also has six SATA 6Gbps ports, pin headers for two USB 3.0 ports, six USB 2.0 ports, a FireWire port and a serial port. The board has an 8+2 PWM design, although this model is using standard MOSFETs rather than DrMOS.

Around the back we're looking at a PS/2 port, eight USB 2.0 ports, two USB 3.0 ports, two 6Gbps eSATA ports, a FireWire port, a Gigabit Ethernet port and 7.1-channel audio with optical S/PDIF out. Overall a pretty well-rounded board and it's already listed for sale in New Zealand of all places for about S$270 which seems a little bit on the expensive side, but keep in mind that electronics prices are usually quite high in that part of the world.

Next up we have Gigabyte's budget 990FX board, the GA-990FXA-D3 and as the name gives away, this board relies on Gigabyte's older Ultra Durable 2 PCB design with a 4+1 phase PWM design. The slot layout is identical to that of the 990FXA-UD3 and so are most of the on-board features too, although the FireWire controller and the front USB 3.0 ports are missing. Around the back we're missing the eSATA and FireWire ports.

Finally we have the 990XA-UD3 which is Gigabyte's 990X based board and as strange as it might seem, this model offers some advantages over the 990FXA-D3. For starters this is an Ultra Durable 3 board with an 8+2 PWM design. As the 990X chipset supports fewer PCI Express lanes we're looking at a total of three x16 PCI Express slots with the primary slot sharing bandwidth with the secondary slot in a dual x8 configuration and the third and final slot has four lanes worth of bandwidth. The board also has a pair of PCI Express x1 slots and two PCI slots.

As with the previous two boards we have six SATA 6Gbps ports and as strange as it might seem, we get a return of a pair of front USB 3.0 ports and the FireWire pin-header alongside headers for six USB 2.0 ports and a serial port. Around the back we have a PS/2 port, eight USB 2.0 ports, two USB 3.0 ports, a FireWire port, a Gigabit Ethernet port and 7.1-channel audio with optical S/PDIF out.
