Definitely need/want dual monitor capability for extended desktop
I've decided to base new build around the AMD Phenom II X4 965 Black edition ($159 plus + $10 gift card at newegg). Despite my status as basically an HTPC user (with some light photoshop and video editing), I chose this chip to buy a little future proofing.
Gigabyte and Asus are equally good. The board you listed is a good board. It is hard to choose between Antec or Lian Li but if you find a Lian Li case you like it would be my choice. Any modern GPU would work for your dual DVI out but photoshop favors nvidia cards but the board allows for hybrid CF with low end ATI (AMD) card like HD5450.
