The new Sapphire Radeon HD 5970 – based upon the acclaimed ATI HD 5970 chipset – is the new world’s fastest graphics card. Its 3DMark Vantage score is an insane 22,000.
The overclocked ATI GPU runs at 850MHz, which is supported by 4GB of DDR3 RAM (itself, clocked at 1200MHz). And all this hardware necessitates three fans an a massive heatsink, making it thicker than your average video card. Outputs include two dual-link DVIs and one mini DisplayPort.
