Windows 7 – How to Set Up Three Monitors

From the page you linked to:

Dual Monitor Ready
This product supports Dual Monitors and has Dual DVI Ports. Dual View technology offers multiple display support on up to two separate monitors. This improves the capabilities and productivity of the user by allowing them to spread multiple windows over two monitors and view them simultaneously. Dual Monitors is one of the simplest, yet most amazing productivity boosters you can add to your PC!

The image shows one DVI, one VGA output and one HDMI port. In this case the HDMI port counts as DVI, though you will need an adaptor for your monitor (unless it has an HDMI input of course). Thanks to @quack quixote for putting me right on this.

Therefore, given the right cabling and adaptors you should be able to extend your desktop onto the second monitor without any trouble.

First of all it depends on your budget. :) You could use Crossfire only if you want to upgrade your performance (by 1.5x to 2x). However, if you want to support 3 or more displays properly, you need at least the Radeon 5xxx series.

There are several Radeon 5xxx or 6xxx which not only give you significantly better performance, but also as many as 6 display outputs without having to go Crossfire.

That said, the upgraded single approach would be my recommendation because:

• You need a 5xxx series or better to support multiple displays
• Newer single cards have 3-6 or more connectors
• Single card gives significantly better performance AND features
• Single card is lower overall power consumption
• Single card will produce less noise

Update Additional note on performance:

Having had some additional experience with Crossfire and SLI since this post, I should also point out that both will (a) increase your CPU usage, and (b) do not always work properly - or even at all - in many games / apps.

The CPU usage is an issue particularly with Crossfire I found, where it increases nearly 30% or more even on a Quad core machine.
