from the way I've been understanding it lately, the 2500+ barton has the exact same architecture as the 3200+ and the 2500+ has really great overclocking ability and stability with adequate cooling, anything better than stock basically. Its got 333FSB compared to the 3200+'s 400FSB, but they both have 512k Cache and then you can go into your BIOS and change the frequency from 166 to 200 incrementally getting there. So then basically you'll have a locked multiplier of 11x200 = 2.2GHz which is the same as the 3200+. I believe I'm going to attempt this because I have a better CPU fan coming in 3 days =) so here in a couple weeks I'm going to purchase the 2500+ and OC it to 3200+
