xlsior, DVI doesn't have a max of 60fps, it's a maximum of 60 hertz. I think you're refering to regular D-sub cables. You might wanna google it and read up
I'm running 1280x1024 @ 75Hz over DVI myself. That's what my graphics settings are set to, and the on-screen display on my LCD agrees with it.
Anyway: according to Google, single-link DVI can handle 165 megapixel/sec, for a max resolution of 1600x1200 @ 60Hz. *however*, if you run at a resolution lower than 1600x1200, you can use the extra bandwidth to crank out a higher Hz.
Case in point, my 1280x1024 @ 75Hz.
