I am currently running two monitors and the setup below. I am thinking about getting a third monitor, probably a dell 2007fp but I might go bigger and place it in the middle of the other two. What kind of upgrades do I need on my video card to allow this? I have one monitor in the VGA and one in the DVI right now, so will I just have to buy another video card?

I want to to be very fast as I will use it for 12+ tabling with no overlap. If any other components besides the video card need to be upgraded please say so. Thanks!

My setup:
pentium 4 3.4ghz, 1.5gb RAM
RADEON 9600 256mb 400mhz
dell 2001FP, dell 2007FP
