CAD is Computer Assisted Development where "memory" is the usual key word there. Graphics design on the other would involve memory and the more important increased demand on video support. Biostar is a little more of a budget board rather then a higher ended Asus, Gigabyte, or MSI model due to the lower specifications. They don't get a number of complaints however like some other "cheapie" makes. They fit in with Abit and DFI for the most part.
