Does anybody know anything about touch screens

Ok I bought a brand new computer last year for Christmas state of the art. So question I did not order a touch screen because I figured windows 8 wasn't going to be introduced until this year, I figured the price on them would come down on the screens which it has and they have got bigger and I figure by christmas this year they will be even bigger for your buck. Well any to my question do I need a different graphics card or anything or should the one I have work with a touch screen its input is the new weird kind so its not vga, it is dmi or something like that so should that work? I mean how do they know they are being touched thru the graphics card or what? I'm still not sure on this?

I'm pretty sure that most touchscreen monitors have a separate USB cable to send the touch commands to your PC. The VGA or DVI connector is purely for video.

That is exactly how they work.

The touchscreens are quite pricey vs comparably sized LCD screens.

Would not a decent trackpad make a reasonable substitute?

I purchased two all in one touch screen computers by HP for Christmas two years ago. One for my mom and one for my wife. Personally my wife Carol and I can't stand the darn things. I took Carols back to where I bought it. My mom loves hers because there is no box on the floor, but never uses the touch screen features. For me I can't stand finger prints on a big monitor, and don't event talk about opening the case for repair or upgrades. Microsoft can keep Windows 8 because I don't need the included software for a touch screen. Windows 8 maybe fine for a tablet, just not for a big screen home PC.
