I have an NVidia 6200 AGP card with component out which I use to power a
1080i/720p monitor with no problem. It's a frontend only now, but that
same card was used in a fe/be box also without any problem. The
particular card I had was the PNY version because of the component out
dongle - not all 6200 AGP cards (not many in fact) have that component
out for high def. Most of the later PCIe cards do. I also have a
6800XT AGP card installed in another fe, but I wouldn't recommend that
even though it's more powerful the card is very long, produces a lot
more heat and requires a lot more power.
Both the 6200 and the 6800XT use the new NVidia drivers (in *buntu it's
