Hey... sorry to revive old topics, but I'm currently looking into upgrading as well. Right now I'm considering the NF7-S motherboard, with either the barton or barton mobile. The Barton 2500+ retail is about $80 on newegg, while the mobile 2400+ OEM is about $77 on newegg. The problem is that I've never done overclocking before so I don't know what kind of cooling would be required for the mobile barton. From what I've read, the 2500+ barton desktop version can be overclocked to 3200+ with the retail cooling. I've also read that the mobile version can easily go up to 2.3-2.4Ghz, but since the mobile version is OEM, I'm at a lost when it comes to cooling. Any help on this subject would be appreciated. Thanks!
