Although they are quite scarce in Europe as we wrote here, FM2 motherboards are widely available in the US of A, and just a quick glance at Newegg.com reveals a bunch of FM2 socket motherboards based on the A55, A75 and even A85x chipset, all ready to be paired up with AMD's recently released Trinity APUs.
The list of course kicks off with the cheapest FM2 socket motherboards based on the AMD A55 (Hudson D2) chipset and are usually based on the micro ATX form factor. The new A55 motherboards range from US $54.99 for the cheapest ASRock FM2A55M-DGS micro ATX motherboard to a bit more expensive ASUS F2A55-M LK PLUS priced at US $74.99. With the A55 chipset, you get a single PCI-Express x16 2.0 slot and you will not be getting USB 3.0 or SATA 6Gbps either. It also lacks the HDMI output and it is limited to DVI+D-Sub in most cases.
The next in line are the FM2 motherboards based on the A75 (Hudson D3) chipset and these start at US $59.99 with the ASRock FM2A75M-DGS. This one comes with six SATA 6Gbps ports and two USB 3.0 ports. The ASRock FM2A75 Pro4-M, priced at US $74.99 will give you two PCI-Express x16 slots (x16,x4), five SATA 6Gbps ports and two USB 3.0, all packed in the same micro ATX form factor. The most expensive FM2 A75 based motherboard currently comes from Gigabyte and is priced at US $89.99.
The last, but not the least, are a couple of FM2 motherboards based on the AMD A85X (Hudson D4) chipset and these start at US $94.99 and can go as high as US $139.99. With A85X, you'll get either two or three PCI-Express x16 slots (x16, x8/x8, or x8/x8/x4), up to eight SATA 6Gbps ports, a couple of USB 3.0 ports, generally better features and quality components, HDMI, DisplayPort and DVI+D-Sub outputs, and support for up to 64GB of memory.
Currently, ASRock, Asus, Biostar and Gigabyte are only four manufacturers but we are sure that all other should join in pretty soon. You can check out the full lineup here.
