Which would be the better buy? Overclocking wiseAMD Athlon XP2800 "Barton"orAMD Athlon "Mobile" XP2500-M BartonI hear the 2500 "Mobile" will overclock to 3200 speeds without a blink.Anyway, let me know what you think.

For the most part (no guaranttees with overclocking computer components) the Mobiles overclock better. They're designed to run at a lower Vcore, so they generate less heat. I'm sure there are other factors in the Mobile design as well that allow them to overclock better.Greg

But will the mobile processor work in a PC when it was designed for a laptop?

Yep, they work great. I visit an A7N8X board quite often, and lots of folks there are running them fine. A couple are even using water cooling to clock their systems to 2.6-2.7Ghz!Greg
