What do you class as cheap?
I know the card thats in my PC at the moment has a dual DVI option, and you can also get it in low profile.
Matrox Millennium G550 Dual DVI
About £85 but its more of a CAD type card than your gaming graphics card...
I'm just using it as it came with it, absolutely hate this PC because I'm struggling to find a good graphics card thats AGP 4x
