Sapphire Atomic HD4870 X2

Zitat

Sapphire Atomic HD 4870 X2 costs saucy €600, but we must admit that this is a unique graphics card in many respects. Apart from the GPU’s water block, Asetek’s cooling provides CPU cooling at the same time. The entire water cooling system, graphics card included, is a pre-assembled and closed circuit.[...]

Temperatures are much lower than on dual-slot reference card and it runs quiet in 3d mode. The core is overclocked to 800MHz and the card packs 2GB of GDDR5 memory running at 4000MHz. Atomic HD 4870 X2 card takes up only one slot, which is not the case with the reference card.

Overclocking the GPU by 6% results in up to 10% better gaming results. Geforce GTX 280 loses by as much as 40%, but note that GTX 295 will be priced lower than the Atomic card although it will be faster. However, if you’re looking for the fastest single slot card around, then look no further than Sapphire Atomic HD 4870 X2, as it will probably keep that title for some time.
