I don't know if anyone hear has heard this but the mobile Barton's (2500+) are unlocked and will work in socket A motherboards... the amazing part is that they will run at stock voltage of 1.25/1.45 (hearing conflicting reports) and people are getting amazing overcocks on them... it seems that getting 2.5 ghz on air is common. I seriously considering getting one even though my current Barton is unlocked... I figure I have to push my current system to the limit until I can warrant an upgrade to AMD64. But just to recap.... MOBILE BARTONS & LOW VOLTAGES = HIGH OVERCLOCKS.
