YES!!!!! TY I just got confused because it said it wasnt compatible with the 6600 agp oh well but after ur reply for the last post i might end up having to get a new psu instead of this.
HUH!?!?! wait. u have 6800. its compatible with 6800. its not with the 6600 agp. im no expert(tho im gettin there..i think) but a 6600 != a 6800(for those who dont program, != means does not equal)
