We are positive that many ATI AIB partners will launch their reference and factory overclocked HD 4890 cards. We know that Asus has its TOP version ready, and that Sapphire, XFX and HIS are also going to do factory overclocked cards.

As you already know, HD 4890 will launch in two versions, overclocked and reference version, but we are pretty sure that both of these versions will use a reference cooler. Non-reference versions will come two weeks after the launch and we know that Sapphire is working on a Vapor-X Toxic version.

These cards will be more expensive than the regular HD 4890's but we believe that Sapphire's Toxic HD 4890 with Vapor-X will be at least cooler, if not even faster. We still don't have a picture of the card but we managed to score a picture of the box.
