i heard some monitors require a dual dvi link or something, like i read somewhere that the 27" dell lcd requires only 1 graphics card, how do some monitors require 2 graphics cards?

doesn't the 30" just require one?
 
No monitors require two video cards. A dual-link DVI cable is like an ordinary DVI cable with an extra set of 9(?) pins in the middle. Only so much information can pass through a single-link DVI cable. Dual-link DVI cables effectively allow double the information to pass by adding those extra few pins, so that resolutions much higher than 1920x1200@60Hz can be ran (such as the 30" resolution of 2560x1600@60Hz).
 
The video cards DVI port must be a "Dual-Link" port to support above 1920x1200 resolutions.

can my x1800xt support 2560x1600, do i need a dual-link dvi then? if so, it's backwards compatible with single dvi?
 
so dual-link dvi cables can fit into the regular dvi ports in the back of my video card but they have this extra pin or something and this extra pin won't cause it to not fit in my video card?

I believe the cables will fit even in cards that are only single link DVI
