hi all, i have just sold my spare pc but they do not want the monitor, so i thought i might put it onto my main pc as a second monitor, my main monitor is a 30" dell at 3560 x 1600, the spare is a 19" dell, 1280 x 1024 ( i think ), will i need a spare graphics card to run this at a different resolution, i currently have 2 x gtx 480's sli, but i do not want to lose my sli as i need it run run games at max res, so will i need a cheap card to go in also to run the second monitor.
