video cards
 

Hello everyone. This is my first post. I'v been reading in here for a short while though. Thanks for all your helpful information.

I feel embarrassed to ask but I'm having a hard time finding good info on this. So, far I only work with SD video but I'm on my way to move to HD soon. My next purchases will probably be a couple of HD cams and a MBP (I also have a G5, see my gear). What I don't quite know or understand when do I need to update video card. is DVI not capable of sending HD? If someone could give me a short explanation on why I need some new video card I will really appreciated. A link will be fine too, I don't mind reading, jeje.

I'm basically trying to learn if I need to get a new card, or matrox, why and how to choose a good one.

I hope is not too much to ask.

Thanks
Osmany Tellez
