When it comes to overclocked graphics card with ridiculous speed Sapphire’s Toxic series is one of the most renowned in the “AMD world”. Today we have Sapphire’s Toxic R9 280X which comes with a massive out of the box overclock of 15% – taking it from 1GHz core to 1.15GHz core, on the memory we see a more modest increase of 100MHz (6.67%). The Sapphire Toxic R9 280X features the respected Tri-X triple fan cooler with a huge 10mm heat pipe and a dense aluminium heatsink. From what I’ve heard and read about this graphics card already the main selling point of this GPU is its ability to offer near-GTX 780 levels of performance for a substantially lower price.
