I've got 3 AM2+ boards, 2 of which are Biostar and 1 Gigabyte. The Gigabyte board is a 780G chip I picked up in 08, it has support for all AM3 chips including Thuban. Than my 2 Biostar boards are 790GX chipsets, one is the TA790GX XE(currently logged on that comp, only reason I'm providing just this board model specifically). 1 of the boards only has support up to the 925/945 C2 Phenom II chips, no Athlon II or newer Phenom II models listed. The other board has Phenom II C2 up to 955, and the first Athlon II chips listed, but no C3 or Thuban processors. Basically it's been close to a year since the last BIOS update, both are solid boards, but upgrade path is slim for AM2+.
