as i said in the other forum:

pci express is newer and better than agp
but that is not to say agp is total carp. if you have an agp port then i would bet that you dont have a pcie port

imo the x850xt pe is the best agp card today. ive seen rumors of the latest generation of ati cards to be released on agp (specifically the x1600)

thats a good price for that card but i say if you dont need it dont get it and 1. see what is on the horizon for agp or 2. just build a new computer

and you should consider more ram
