Yes, I am on the internet every day absorbing as much as I can but I was hoping someone knowledgeable could explain to me in just a few sentences what exactly a vid card does in relationship to the CPU?
It offloads the part where the computer has to render a visual output to a monitor. You don't have to have a video card, if the computer has another way of providing output (text terminal, for instance).
I thought when I am watching a movie, the GPU on the vid card would be doing all or most of the work for the pc. Can anyone put into percentages how much work the CPU does and how much work the GPU does while watching a movie?
No, because it depends on a lot of factors including:
- What kind of video it is
- What kind of video card you have. Traditionally, lower end video cards had better video decoders.
- What drivers you have installed
- How the codec settings are set up
- What software you're using
- If the software supports CPU offloading to GPU

It seems these super expensive, high end vid cards are more for gamers and not people like me who use their pc's for the internet and watching HDTV.
No, and often times in the past, the high end video cards had the last generation video decoders.
Thinking of ways to spread around the work the pc does, I am considering two vid cards. One card plugged into my HDTV and the other plugged into my HD monitor. Doing this, I am assuming I wouldn't need to purchase a top end card I could, instead, purchase two "medium rated" cards that can easily do HDTV and internet stuff.
Don't you have a Z77 board? Just use the Lucid Virtu feature on your motherboard (http://www.anandtech.com/show/5728/inte ... -biostar/2
). This will let you use the discrete GPU for heavy lifting and the iGPU for video decoding. Or something.
