Allan,
Thanks for that very detailed reply. I've read the sheets you've linked and attempted to understand as much as possible. Based on experience, I would probably say the newer chip would be "better" than the older chip. But I'd only say that if I were comparing oranges to oranges. In your expert opinion, given the comparison is being made for hardware requirements for a piece of software, would you say the newer HD 4400 is "better" than the GMA 4500? Or is it a different type of chip?
Thank you
