I recently purchased a Gateway DX4831-01E (6GB memory, Intel i3-530 processor, 1TB HD, 300 watt power SUPPLY, PCI express SLOT) for $550.  I don't know anything about video cards but heard that some cards have ATI eyefinity technology that allows 3 displays to be used with the one video card.  I only want the 3 displays for internet surfing and do not need a high end video card since I do not do any gaming.  If ANYONE can find a video card that can run 3 displays and only requires a 300 watt power supply computer that would be great, but I am guessing that I will need to change out my power supply to a HIGHER wattage rated power supply.

Please provide a recommendation for a low cost video card and a low cost power supply that will meet my needs and include a link to a website where I can purchase it.

I am also not sure if I will need one of the displays to have a display port output or if I can use my display with a HDMI output and get a connector that converts a display port output on the video card to an HDMI output.If you don't care about games, you could use this video card. You would just need a S-Video to VGA converter, depending on what you plan on hooking up to the video card.
