The only use for such an adapter now is to connect a DVI monitor to an old AGP (probably 4x) graphics card in an old PPC Mac.
oh, that´s good that someone explained that AGP to DVI connectors can be used to connect AGP stuff to DVI stuff, he probably did not know that when he asked for one.
but jokes aside, i recently tried to find one here in europe and i gave up after 6 months.
instead i have 3 AGP to VGA adapters now.
which in theory would be fine since i only use monitors with both types of connections - but now i have to deal with that other issue with >3 meters VGA cables again, which are also close to impossible to find (unless you want to spend 200 bucks.) a DVI adapter would have solved
that problem.
so AGP to DVI
is something which has a legitimate place on our wishlist, just as the ATX to QS/MDD adapters do.
