Yes it will . I used to have 3 monitors hooked up . A 21" , a 17" and a 15" . But now I just have 2 - 21" Nokia's . If my desk was a little bigger I'd have 3 of them .
This will be great . By all means if you can add at-least a second monitor you won't be sorry . Having a bigger desktop alone is worth it . I've had multi monitors for the last 5 years and I won't ever go back to just one .
