After market coolers, higher clock speeds and also longer warranties and crazy bundles are something you normally don't see from day one. So what's different with the HD5850 Toxic? Lets find out!"
Pre-overclocked graphics cards have been around for years and, while not for everyone, can offer that extra sliver of performance if you're willing to foot the bill. Sapphire has taken note, and decided to really push the boat out with its new Radeon HD 5970 Toxic. Not only do both GPUs ship with a massive 24 per cent overclock, but the card comes fitted with twice the GDDR5 memory of the stock model, and a massively upgraded cooler too. Make no mistake, this is a pre-overclocked partner card done to the limits of what's possible, to the point that the production run will be extremely limited; Sapphire says that less than one thousand units will be produced.
