Secondly, I assume you mean a 2800XP Barton; this isn't 2.8GHz, but performs like a P4 of 2.8GHz (or better). I can tell you what the response around here from a lot of people will be; don't get either. Get an Abit NF7-S SoA motherboard, with some TwinMOS PC3200 w/Winbond chips and get a 2500 XP-M
mobile Barton (as per
