How many monitors can I hook up on this computer?

i suck at hardware.

I have Intel Chipset Family G33. It sucks hard.

I already ordered it, It is actually a very good and considerable computer for just $498.
I would build a computer, but I do not have much experience with all that, so I just bought a cheap complete one. I will just change the graphics card after I buy a better one.

P.S. I don't play any games like Crysis at maxed, cod series or anything. I mainly chat with friends and play Minecraft & RuneScape, I just like to have a nice and fast computer If I ever move on to another game.

I looked at used ones and stuff, all of them are old and XP OS. I would like to buy new electronics, atm I'm looking at monitors, I want like 2 20" monitors and a nice computer desk.
