Just bought a GA-MA78GMH-US2H, working perfectly with my Phenom 920, and 4 gig of Crucial 1066 memory.
Dual booting XP and Windows 7.
Picked up all 3 at the Wilsonville, Oregon Frys last week for $313.
Processor $180
Motherboard $84
2x2 gig DDR2 1066 Crucial 7-7-7-24 $49 (With a $10 rebate that I tossed in the trash) guarenteed to run at DDR2 1200.
........and no sales tax in Oregon...joy-joy.
Reinstalled my trusty ol' BFG 8800GTS 512 OC.
So far I have pushed the Processor to 3.2ghz, without changing anything but the FSB. Everything is completely stable and behaving excellantly.
