by techPowerUp! (Dec, 2008)The included CPU waterblock seems to be good enough for mainstream processors but I have my doubts that the radiator can handle the 4870 X2 plus an overclocked and overvolted processor.
by techPowerUp! (Dec, 2008)Still, for users who are not looking to do a lot of tweaking with their system and just want something that is fast and special the Sapphire 4870 X2 Atomic is definitely a cool toy.

What People Are Saying Give it to me straight
Applications
by techPowerUp! (Dec, 2008)The HDCP output features the usual HDCP+Audio, which allows easy setup of a media PC.
by techPowerUp! (Dec, 2008)Also included in the package is a large software bundle, loads of cables and everything else you could imagine.
Memory
by techPowerUp! (Dec, 2008)Both GPUs, the PCI-Express bridge chip, the memory chips and the voltage regulation circuitry is cooled.
by techPowerUp! (Dec, 2008)The GDDR5 memory chips are made by Hynix and carry the model number H5GQ1H24MJA.
Multi card
by techPowerUp! (Dec, 2008)CrossFire will work with any HD 4870 / 4870 X2 from any mamn The card has one six-pin power connector and one eight-pin power connector.
by techPowerUp! (Dec, 2008)A single CrossFire connector is present to link this card to another HD 4870 X2 or HD 4870.
Overclocking
by techPowerUp! (Dec, 2008)These overclocks are slim, I would have expected more from watercooling.
by techPowerUp! (Dec, 2008)Back in HD 3870 times Sapphire released a special overclocked edition of the HD 3870 X2 called "Atomic.
Power
by techPowerUp! (Dec, 2008)The power consumption of Sapphire's card is the highest we have seen so far in the labs which is mainly because of the overclocked frequencies.
