Do I have enough Power Supply for Duel 30' Monitors?

Power from the PC not should not effect the monitors. Its the graphics video card that decides whether or not it can power the monitors. First check the video card and see if it has duo monitor output, this can be VGA or HDMI or DVI. The native resolution of the Monitor is 2560 X 1600. You will need a medium end graphics card to power this, your pc has a Nvidia 9800GT with 512MB of ram and two DVI outputs. This card will definitely work. (I checked the NVIDIA Website for a 9800GT resolutions). You might see a little chopiness if you try some highend game, but for video editting and photo manipulation you do have enough power. Your System Memory of 8GB is fine too. You will have no doubt a kick- system.
