My vote is the Radeon 9000 oem.
Available for not alot of money, with 128mb of quite slow memory on them, they still do a sterling job of most games on the shelves. Its not the Pro version...just a regular, unbranded OEM offering that I would happily put in most people's PC's cos they are 100% reliable, have good drivers, look sharp and do colour 3d very well.
What about you?
