Does Hd 6870 have Dual Link DVI? Looking to buy a new monitor

I am looking to buy a new monitor (BenQ XL2411Z) and I was wondering if the HD 6870 has a dual link DVI that is compatible with the monitor. If it has one, how can I link my existing monitor (some ASUS one) with the new monitor. Basicly is it possible to have the BenQ XL2411Z with another monitor that is 60 Hz? Thank you and sorry for the bad english.
