Dual external monitors? I am trying to switch from using my desktop to my macbook pro as my primary machine.

I have 2 monitors (each 1600x1200 resolution) I'd like to use as external monitors for my macbook pro (from 2013).  Both monitors support VGA and DVI input (along with s-video and composite, although I've never used those before).  

Looking at the laptop, it has 1 hdmi port, and 2 thunderbolt ports.  

The 'about this mac' reports I'm using osX 10.10.4, with a early 2013 15-inch Retina display.  Graphics card is nVidia GeForce GT 650M 1024 MB.

How do I find out if this is possible?  If it is possible, how do I do it?
It's possible. You can run one monitor off the HDMI port and another 2 off of the  Thunderbolt ports. You can get adapters for both of these. 

There's more out there than this but here's one Apple sells.

BTW: Thunderbolt ports can work Mini Display port adapters.
