" Every once in a while you see one of those products that makes you wonder. Well, two in a week is a pretty rare occurrence. The Sapphire HD4870x2 Atomic is the second of the two. Sapphire usually pulls something special together for its Atomic versions. Last year with the 3870, it was a special vapor chamber cooling system that worked extremely well when cooling was needed for those all night frag fests. Well, Sapphire has done it again with this iteration on the HD4870x2. This version does not use vapor chamber cooling, but rather a fully sealed water cooling system complete with pump/CPU block radiator and full coverage cooling block on the dual GPUs. To go along with this Limited Edition special cooling solution, Sapphire has upped the ante by pushing the clock speeds on the two RV770 cores to 800MHz and to 1000MHz (4000MHzeEffective) on the two gigabytes of GDDR5 memory that runs through a 2x256 bus.
