Hey guys I was looking into getting this monitor: http://www.newegg.com/Product/Product.aspx?Item=N82E16824009222
The graphics card I have is a MSI gtx580 twinfrozr with 2 DVI output ports and a mini HDMI which I currently have hooked up to my monitor via a DVI cable.
This monitor I'm looking at has a 2ms response time and I have heard that DVI cannot support this but HDMI can. So does anyone know if I could just use the DVI connection and get full performance or would I have to buy a mini HDMI to HDMI cable to maximize its potential.
Thanks.

The only difference between DVI and HDMI is that DVI carries a digital video signal while HDMI carries both a digital video and audio single through a single cable. There will be no differences whatsoever in picture quality from using a DVI cable instead of HDMI.

Quite simply (as I didn't watch the videos but thought I might mention this in case someone is deaf or hard of hearing), DVI and HDMI sends and receives signals as 0s and 1s: it's either on or off. But the only difference, like Razear mentioned, is that HDMI carries audio and video but DVI only carry video signals.

Perhaps this is just me, i have Have a DVI to HDMI cable that i use from my gforce card to my hdtv. It carries audio from my dvi pc card out into my hdmi tv.

This is contrary to what is being said here. Anyone else have this same situation?

Then perhaps the DVI to HDMI adapter is a special kind of adapter that is provided by nVidia or AMD?

"Unlike a generic DVI-to-HDMI adapter, the included dongle includes pins for connecting the audio."

You're sure you didn't connect the audio separately or to the converter cable? Because it's not possible otherwise.
I tried to find the pins that carry the audio on the HDMI and see if they are missing on DVI but can't really find them.. but the pinout site confirms that there's no audio on DVI:

"a DVI source can drive an HDMI monitor (...) but the audio and remote control features of HDMI will not be available."

You don't HAVE to connect the audio cable to the converter cable or an adapter.

Here's another one:

Aah so I guess it's a driver thing? No wonder I couldn't find audio pins..

Sorry dglenn247 you are right, it is possible.

IF you want sound out of monitor then HDMI if you want to watch off bluray or HDCP content then you need hdmi 1.3c .
If you want a sound system hookup soon then get hdmi.
If you want a good picture and will only use pc audio or headsets then dont waste your money on a hdmi connection unless the screen is really worth it.
