Hi I have a asus p5q3 deluxe like this: Google Images ... %26hl%3Dda And i use this gfx card: Ati 4870 radeon 1 gb ram , that have 2 dvi ports. I then use the one port for my main screen and the other for my Phillips 42 " in extendet desktop mode, so i can watch movies and stuff on that screen. Then i want to add a 3 screen, so i can game on my primery main pc screen and watch my programs running on the 3 screen while i play a movie or something else on the phillips 42". secondary screen. The question is: I heard the best thing to do is get another gfx card, but i am in doubt how this would work and what sort of gfx card to choose.from pci or pci express or size ram or brand..ect.
