The reason your friend gave you that advice is because PCI-E available now, is the future of computing. PCI-E will not yield better performance than and AGP solution. At least not yet. If I were piecing together a new rig, PCI-E would be one my choices.
it goes more with ur mobo then with PCI-E vid cards, u want a mobo with PCI-E for future cards that will take advantage of it, cards out now dont take advantage of it, u will have to get a mobo with PCI-E (and therefore u will have to get a PCI-E card) if u want to upgrade ur vid card using the same mobo
....well, at least i think so......and a agp card now will have a really low resell price(if any) in the future
I guess...but for now I am skeptical of it. No games/or videocards can take full advantage of it right NOW. They will be in a couple of years. However, what is the point of buying a x800 XT PCI-Express and spending the extra money. In a couple of years they will have new motherboards, processors and everything... Your AMD 3500+/mobo/ and definately videocard will be out of the loop and you will have to upgrade anyway............
