AGP bus (PCI mode)

I've noticed that on this Nvidia TNT AGP card on the properties page for the
device it claims to be using the AGP bus with "(PCI mode)" in brackets next
to it. Does this mean that its running on the AGP bus or not?!

Also - out of interest if this (32MB) card is running in PCI mode (and
therefore on the PCI rail and therefore at a reduced capacity in terms of
what it can reach), what would be benchmark higher - this card or a Geforce
MX440 PCI card?

If it's an AGP card, in an AGP slot, it has to be running from the AGP
port (not actually a bus since there's only the one device). Whether
that bus is using ALL available AGP features is another story, might
depend on the driver version, motherboard chipset and chipset driver
(version and correctly installed).

I wouldn't worry too much about it though, there isn't a lot you can
do to squeeze any significant amount of extra performance out of a TNT
card except making sure you have the chipset driver installed.

A MX440 PCI card would be faster, though either is pretty slow, a
Geforce 3 would run circles around either, let alone newer cards.
