I like my PowerColor Radeon 9250 cards. I guess those made by Sapphire and others should be good also.
They are cheap, they work well, and XP has the driver. Plug in and go. I can now fast user switch without problems, unlike when I had other video cards installed.
By the way, I don't see any difference between DVI and analog. Both look good to me.
I have dual 17 inch LCD monitors.
