If you read the whole post, I don't think it's misleading. Perhaps I could
have changed the order in which I said things, but I did include the comment
"in general," and I feel that I clarified the situation in sufficient
detail. I also specifically mentioned that he should check with the
motherboard manufacturer and ask them if a card rated to work in an
AGP2x/4x/8x slot will work in his motherboard. I don't see how I could be
any less misleading than telling him to check with the actual manufacturer.

Keep in mind that plenty of cards capable of AGP4x or even AGP8x work just
fine in AGP1.0 slots -- Leadtek, Visiontek, and PNY are all brands that I've
personally confirmed this with. I'm currently running three systems with
AGP1.0 compliant motherboards -- all three are old BX chipset motherboards
with AGP 1.0 1x/2x slots. Two of these systems are running "AGP2.0"
compliant cards, one of which is a GF4Ti4600. The third is running a
Geforce 5200FX rated as "AGP8x" which runs at 2x in this motherboard. This
demonstrates that cards and motherboards that properly followed the
standards "can" work fine -- I'm not saying they "will," I'm saying they
"can." The cards and motherboards are supposed to be keyed to prevent a
mismatch, so if they can't work together, the card isn't supposed to fit.
Unfortunately, discrepencies in following standards has led to the somewhat
confusing situation we're now in.
Note that I'm not saying that he necessarily "doesn't" need an AGP1.0
card -- he may in fact need just that. What I'm saying is that if a card
says it supports AGP2x, and a motherboard says it supports AGP2x, they "can"
potentially work together, and if everything was designed properly, they
likely will. If they can't work together, they are "supposed" to be
designed so that the keying won't allow the card to be inserted.
