7850 Question regarding 120hz monitor

Hi, in short I am purchasing two 7850's: http://www.overclockers.co.uk/showproduct.php?prodid=GX...

I am wondering whether or not they are compatible with this BenQ monitor: http://www.overclockers.co.uk/showproduct.php?prodid=MO...

Essentially, as most are probably aware... the monitor uses 120hz for gaming fluidity, now my concern relates to the outputs on the 7850, specifically the DVI-I dual link and whether this is compatible with this monitor, I've seen that it uses DVD-D Dual link? Does this mean I won't be able to use this monitor with these cards for 120hz gaming?

Apologies, when it comes to DVI connectivity I have no clue, so figured best to ask before I spend £600.

Thanks in advance.
