We saw Sapphire really mix it up recently with the HD 4890 ATOMIC version of the card. The company hasn't stopped there, though, now choosing to do even more with the model. ATI partners really don't have the range of graphics cards to play with like NVIDIA ones. What this means is that we tend to see companies offer more variants of the same model.
The HD 4890 has always been a pretty impressive card. While it was never the holder of the performance crown, it did manage to offer some serious value for money and for so many people this is more important than a super fast card that they can't afford.
The main feature to the HD 4890 we're looking at today is the extra memory which brings the card to 2GB. We've never been a huge believer of such huge memory amounts on graphics cards; there tends to be a point where performance flattens out. With that said, though, we'll find out what else Sapphire is able to offer us with the HD 4890 2GB Vapor-X today.
