@aaron686:
For the average consumer, they'll actually be looking at the commercials and shops computers where the worker will 'suggest' their opinion on a perfect computer. Intel still dominates among average users and prebuilt buyers because they advertise and have commercials.
That's why there are still people that think Intel is the only Company producing parts for Computers, they don't know about ASUS/Gigabyte/MSi/Biostar. When it comes down to it I started off with a computer that had an AMD processor, Nvidia 4400ti graphics, and an HP logo. If I hadn't gone for that AMD prebuilt, I probably wouldn't have known AMD existed until I began doing research on building computers myself.
