Sapphire’s Radeon HD 4870 Toxic edition features the Vapor-X heat pipe cooler based on Sapphire’s Vapor Chamber Technology. Vapor-X makes it possible a cool 43°C at idle and a 65°C under load. This Radeon HD 4870 is powered by the RV770 GPU (with 800 shaders processors), has 512Mb of GDDR5 graphics memory with a 256-bit interface and has some overclocked frequencies (memory: 1000MHz, GPU: 780MHz).

In conclusion, my final recommendation on the Sapphire Radeon HD 4870 Toxic graphics card is very good but at the moment it’s nearly impossible to procure. On its own accord the 4870 Toxic would occasionally reach the level of performance seen from the GeForce GTX 260, but never completely dominate over it.
