In hindsight, I would have bought a Display Port Monitor or a second card, both options would have been cheaper and less problematic than the Adapter, but I already had 3 screens. If I want to run three 24" monitors, all of which are DVI only, from this video card -- is it possible to convert either the HDMI or DisplayPort to DVI? If so, how? And which one is easier/cheaper to convert? With my graphics card (Geforce GTX 275) I got an HDMI-to-DVI adapter which looks like the "HDMI Male to DVI-D Female adapter" at monoprice.com and works fine.

Yeah, the way the Radeon hardware works, is that one display circuitry drives both the DVI2 and the HDMI port. So you can't have them both hooked up at the same time. Therefore to get 3 monitors, you have to do DVI+DVI+DisplayPort, or DVI+HDMI+DisplayPort. DVI+DVI+HDMI is unfortunately NOT an option.
