Yep, any good video card will work fine. You can also buy external hardware for this. But again, the price adds up to the amount of a video card. So im not going to get into that. Since getting a video card is alot better way.
I suggest getting a good video card. You can connect your TV up, while having a good video card you can injoy. But if you want to spend the minimun, then go to radio shack. Tell them you need a special card to connect your TV to computer, vice versa. This card slides in your PCI, and cost around 50$.
