Sapphire HD4890 1GB Atomic PCI-e
Video Card
Last week, we had a nice close look at Sapphire's overclocked
HD4890, known as the Toxic Edition. This week, we are taking
it a step further with the Sapphire Atomic Edition. For those
not familiar with the Atomic Editions, this is the cream of the crop
for Sapphire cards. The Atomic editions have the highest
clocks, the best cooling and the best bundles. They also tend
to be very limited production runs with a price that represents that
scarcity. The
4870X2 Atomic edition we reviewed last December was an absolute
treat of a GPU, and a product that was both rare and impressive.
Will the HD4890 Atomic Edition live up to this rare pedigree?
