Sapphire Technology today announced the release of the new HD 4870 Toxic videocard featuring its unique Vapor Chamber Technology cooling system. ATI 4800 series cards are known for their performance - and their toasty warm nature. Sapphire has equipped its Toxic Edition card with a dual slot Vapor-X cooling solution that combines a three-heatpipe cooler with a thermally-controlled fan with external venting to more effectively cool the card at lower noise levels than normally found on reference-card designs. The Toxic is no reference design for that matter. This edition from Sapphire sports 512MB of high performance GDDR5 memory clocked at 1000MHz and the GPU is factory-overclocked at 780MHz. Pricing and availability were not available.
