They showed some at Computex but none have been available in retail yet, I think. I would give you a link but I've no clue which website carried it (I looked through all the Computex coverage at the same time...got lost).
Probably MADShrimps or The Tech Report. Or one of the other dozen websites. I'll try and look.
Edit: I think I might be talking of some Conroe Motherboards. Err..ignore my post.
BTW, there is absolutely NOTHING wrong with your Opteron 165 @ 2.6GHz. It's actually faster than an AM2 5000+ @ 2.6GHz that has half the L2 Cache.
