It's going to be (if everything is confirmed) the Micro-ATX board to get.

Nevertheless the Biostar 6100-939 is also a great board, i have taken it to 315 but at 2T. If this DFI is able to get to 320 or even 300 at 1T i'm switching boards.

The non SATA 2 support is bad, given the new HDD's that are coming out.

Now the absolute m-atx board would have the SB600 southbridge chipset and a better placement of components (like the Biostar), that ATX cable is going to be awfull for most m-atx cases, like Q-pack and the Silverstone Sugo SG01. All this and 300 with 1T mem support.
