Unlike reference cards, XFX’s HD 5670 1GB comes with CrossFire connectors. This means that you can boost your graphics performance by adding another card. However, the HD 5670 isn’t quite aimed at gamers so we’re not sure that many users will opt on CrossFire, but the mere fact that it is possible with XFX D 5670 1GB is pretty neat.
Two Redwood chips can score a nice frame-rate for gaming at 1680x1050.
