External Graphics Card

[BartSimpsonN7]

Hi everyone,
I want to buy a third monitor for my Desktop, mainly to be used for Spotify and Web-Browsing. As my graphics-card (Radeon 5570) only supports two monitors, I need to purchase an External Graphics Card. I have my current two monitors hooked up via VGA and DVI and I am not sure whether to buy an external VGA or if an external DVI graphics card would be better. Does anyone know if it matters if I have two VGA's and one DVI, or the other way round, or will it only work with one of them (VGA or DVI)?
Help is really appreciated!!!

DVI would be better quality since it's digital and not analog (VGA), so it's going to look better in general.

Like CarnageX said, DVI is always going to be better. VGA should be obsolete in my opinion.
