onboard video vs a video card, power and cpu usage
I am building a carputer based on an AMD Mobile 2400+ chip (underclocked to 25 watts), and trying to decide what motherboard to get.
seems most of the best motherboards don't have onboard video. e.g. abit nf7-s. (nf7-m doesn't have soundstorm) with decent video cards being dirt cheap--like an older geforce-- the only things that really matter:
1) does onboard video use more or less power than a video card (either PCI or AGP)?
2) does onboard video use CPU? in other words, will my cpu usage go up from using onboard during normal usage.
