What graphics card do I need to run 2 monitors?

[Toby39]

Hi guys, I am using a hackintosh with a GA-Z87X-UD3H mobo, and I am running Mavericks.

When I look at the System Pref. and look at Displays, I don't see how to activate the second monitor.

I assume my graphics card can't cater for this ... or is it something else I need to do?

I run my main monitor on DVI, and the second monitor is connected via VGA (no signal).

Thanks

PS: I have just looked in the BIOS f10b, and the only options for monitors seemed to be the "initial" monitor, which was selected as "PCIe 1". There didn't seem to be any setting for additional monitors. However, when viewing the BIOS both monitors worked fine - the 2nd was a copy of the 1st. When I exited the BIOS it couldn't seem to boot up the OS (stuck in a loop), until I pulled out the VGA cable connecting the 2nd monitor.
