Well if you plan on overclocking then you should probably go with a 590/570 board. I don't know about other nForce4 boards, but mine has extremely limited overclocking options. Basically all I can do is raise the bus speed from 200 to 300 in intervals of one, and choose from 4 preset RAM ratios. I've tried looking for an HT multiplier, but come up empty. I've got my X2 3800 up from 2.0GHz to 2.25GHz, but I'm handicapped from here due to the lack of an HT multiplier.
