"The ATOMIC series of cards is one that we really do get excited about when it comes to Sapphire products. Unlike a lot of other companies who overclock, Sapphire tend to really mix it up with this particular series. We don't only see some serious clock speeds, but also something fancy in the heatsink department which always helps bring the card to a new level.

With the bar set high for the HD 4890 ATOMIC from Sapphire let's not delay any longer and see what exactly is going on with the card and find out if Sapphire is able to impress us with this ATOMIC version like other ones from the series have in the past."
