If I were you I would e-mail the manufacturer of the motherboard you plan on buying and ask if that new cpu is expected to boot up properly in that motherboard without needing a bios update first. That way you'll have a response in writing from the manufacturer that you can remind them of if there is a problem. Us anonymous internet folk can say anything, but if we're wrong it's hard to hold our feet to the fire. Not to discount contributions on forums like this, but in this case we're talking about a cpu that hasn't been released yet, so noone here will have actual experience with it yet.
Good Idea. I think i'll do that.
Btw, I was thinking. Aren't the "first wave" of a new CPU usually buggy and bad (compared to later models)? If that's the case then wouldn't I want to hold off on getting an e7200 until the bugs are worked out?
Thanks.
