Help setting up two monitors with a 5770 HAWK

I have an MSI 5770 HAWK that's currently connected to my monitor by a DVI cable. I'd like to add a second monitor that's idential to my current one. Trouble is, my gfx card has 1x DVI, 1x HDMI and 1x DP, while the monitors have 1x DVI and 1x VGA each.

What's the ideal way to go about setting up this dual monitor system?

Thanks in advance :-)
