i am now using intel 815ep,and 845pe and newer ones do not support v5 agp,how about 845d? 848 or even via kt333,kt400 ,or nv nforce 2 nforce 3?
my system runs slow but i still wanna use my v5 agp,so i wanna choose the best chipsets fit for v5

seems kt333+8235+barton is the best choise

Yep, this combination is the fastest possible for an AGP machine.
