Eyefinity/Active Adaptors question

[Makhaira]

I've got a HIS 7950 Boost variant, and I'm thinking of moving to a 3 screen setup.

At the moment I have a monitor connected via HDMI, and another via DVI. These two monitors don't have DP connections, so whatever I do I'm going to need to keep them connected via the DVI and HDMI.

Two mini-DP ports are available on the card.

What are my options for linking up the 3rd monitor (it may/may not have DP), and what adaptors (active or otherwise) will I need?

Many thanks!

Sorry I should have said, the two existing monitors only have HDMI and DVI, so using 2x DP isn't an option. I'll update OP.
