I hope that someone can help me out. I am trying to find out which mobo would be a plugin replacement for the one I currently have. It is an Asustek P4G533 la with an 845GL chipset and a 400FSB.(socket 478) Would like to find one with a 533FSB. Hoping to go from 2.4GHz P4 to a 2.8GHz P4. 2.8 is 533FSB and not compatible with old board. Also, what type of performance difference would I see from this? Thanks from a newbie.
