OK, the Radeon 7500 looks like a keeper. It will run the 20"er, and needs no mods. I'm no ingineerin' genius so that's the model for me, and until now it's been my hardest and longest researched choice to make. Thanks for making it that much simpler. Instead of all that research I should have known better and come here first.
