When shopping for a new desktop computer, I'd like to get one that allows me to use two monitors. Is that something that most current-generation video cards can do (in late 2012), or do I need to search for a specific graphics card, or specific attributes for a card?

I've Googled the question but most answers talk about how to figure out if a computer that you already have can support dual monitors (generally, by plugging two monitors and seeing if they both work). Is there some key terminology that I'm missing in my searches?
