"There has been a lot of speculation about how near to the Titan X the Fury X gets. Much has been said about AMDs relative silence on the subject. That stupid assumption that if they aren't shouting about it from the rooftops that it doesn't get close. Sure it doesn't always match up to the Titan X, but equally it's never disgraced no matter what we threw at it. It isn't even aiming at that card anyway. Given how much of a surprise the GTX980Ti was when it released and the lengthy development time for any graphics card we'd assume that it was intended to go up against the GTX980, and if that is the case then mission completed with honours. Against the GTX980Ti it's, if anything, even more impressive. Both at stock the results are seriously close, yet the R9 Fury X costs less. There is almost nothing not to like. If you are hoping this is an overclocking beast voltage options are locked out, you can tweak the 'max clock' and power target but we didnt get anywhere with ours. Seeing as this will be a reference design only we dont think the vendors will get the chance to play with bios tweaks etc so it may well be a card to fit and forget and not one for the tweakers (going by how ours responded)."
