As I understand it, I need another VGA card in order to use another monitor. My computer is a Dell Inspiron 560 with Windows 7. How do I know what kind of VGA card is compatible with my computer, and how do I know if my computer even has that kind of, uh, port for another VGA card?

I did the Specs thing. By looking at the back, I've got four slots, one of which is being used for my internet (the card being the very first thing I got when I bought the computer). And there is only the one port for me to plug in a monitor cable.

I don't exactly have the best hardware for takin' pictures, so they're blurry, but here's what I've taken:

Yeah, I'm not going for high-dollar. Something affordable.

And if I got a video card, I could it put it in one of my PCI slots (or whatever they're called) right?

That's kind of hard to do when you have no idea what the price ranges are in the first place. Do these things go for hundreds of dollars, or thousands of dollars?

Hm. $50 is definitely affordable. $200 is probably the most I would spend if need really be, and it'd need to be worth that much money.

I like to play MMO's on my computer, though I usually use it for more movies. I've recently done something about my interest in video making, and I notice a lot of people do that sort of thing on two screens, so I was curious, and figured I'd ask about it. I do have another monitor that I picked up at a garage sale, so that's available if I ever do decide to get a card.

for about 100 for lower end...maybe capable..and 200+for a good one that will defanately..ie Asus ENGT440/DI/1GD5 nVidia GeForce ...about 100 bucks
or Asus ENGTX560 DCII OC/2DI/1GD5 nVidia GeForce ...about 200 bucks

Okay, now when you talk about how the more expensive are better. How exactly are some better than others? Do they just stop working? Do the graphics just have more pixels? We are talking about cards that just allow for another monitor, right? If I got another card, would it screw with the original?
