Pentium III video card recommendation needed

Hi all,

I'm upgrading an elderly PC with onboard video at the moment, and I
figure it could use a new video card, but my memory has failed me as
to the best video cards to use with a high-end P2 or low-end P3
system. Suggestions for decent PCI cards to pick up on eBay would be
much appreciated, without going overboard and getting something that
will be throttled by the slow processor. Does a TNT2 sound
reasonable, or will it benefit from something a little faster?

Many thanks,

Dave.
