Bent pins is no good.. I've never had the problem of bent pins, and if I ever did, I'd just have to suck it up and RMA or replace. If I somehow didn't have the option to replace it or RMA it, and I didn't know what I was doing, then I would take it to a computer shop and see if they couldn't so something about it. I hear bent pins are really sensitive and something you don't want happening to your stuff.
That's a great motherboard otherwise. I'd return it, unless you can't?
If you call Asus, make sure you go over everything with them. They'll void a warrenty in a heartbeat to save a buck, so I hear.
