It's an excellent board, however I do NOT recommend ATI graphic cards. Their drivers are flaky. The MB easily unlocked my Phenom II x 2 BE to a 4 core configuration.
I've had one driver problem with my HD 4770, and two with my GeForce 6800. It's all based on personal experience nowadays, ATi drivers have improved a lot compared to the Radeon 9000 series era. nVidia a few months ago released a driver update which caused some cards to overheat. Just because the motherboard unlocked your Phenom II X2 to Phenom II X4 doesn't necessarily make it a good board - many boards can do this, and also it depends on whether your CPU was a fault Phenom II X4 or not.
