Hey guys, i just got a lcd, so im thinking of retiring my 17" CRT, then i was browsing and i saw a mention of dual desktop? i was wondering how that would work, i know i would need a second pci display card for the monitor but it is anything like doing desktop stretching? or is it like having 2 computers, what happens when u full screen a game? and any other things u might think worth mentioning, thanks.
