Thanks for the response! I'm not sure what the II stands for. In fact, I may be wrong in thinking that there is a "II" at all.
Another question: AMD/ATI are the same company, correct?
AMD acquired ATI, so technically ATI doesn't exist anymore.
They were, but ATi no longer exists as a company. The cards are all now all made by AMD.
As for the questiion of the Sapphire II designation, iirc that means it has a second generation cooler and card layout. Sapphire are other AMD partners make some changes to the standard layout of the card in many occasions. The standard layout is often called the "reference card". Most first generation cards are actually reference cards but with partner branding on them. For example I have a HD 3870 that I bought the week it was released. My card is a Sapphire but it is stamped on the card that it was "Built by ATi" and has the first generation cooler design which makes it rather bulky. All Sapphire did with my card was put stickers on it and sell it.
So that card most likely has a custom sapphire BIOS and cooler layout along with some card layout changes.
AFAIK, AMD disallows changes to the reference design on newly released cards. I know Sapphire makes many changes to the reference design, but I have never heard of the II designation. I only ones I know of are Vapor-x, Flex, Atomic, and Toxic. Obviously they make 2 fan and possibly 3 fan designs are usually there is no designation like that, just a model number change.
"Built-by-ATI" is sort of like a Engineering Sample. I believe Sapphire had/has ties with ATI (now AMD), so B-B-A and Sapphire stuff were both made in the same lab. In fact I believe they are still the number one manufacturer of AMD graphics cards.
