DVI comes in 3 (almost 4) flavours, DVI-D (digital data only), DVI-A (Analogue data only) and DVI-I (Integrated, both analogue and digital). The almost flavour is DVI-D dual-link, which carries more data than DVI-D (twice as much, who'd-a-thunk..) DVI cables can be any of the three types, the difference being which pins are hooked up. Most cables support the full pin-out, and therefore all the flavours. All graphics cards these days output either DVI-D dual-link, or DVI-I, depending upon the resolution you ask the graphics card to display. DVI-I can be converted to a VGA DSUB using a simple dongle. Any card that comes with a DVI port also comes with the dongle. I'd also recommend an nvidia card. The amount of memory available on a card limits the amount of 3D textures that can be loaded onto the card. If you aren't worried about gaming or 3D, then even a 32MB card should be able to handle two double buffered 1600x1200 displays. A 128 MB card will perform the same as the equivalent 256 MB card (or 384/512 MB, or even some cards now with 640 MB). Cheers Tom
