From ebuyer: As per our terms and conditions and in line with the Sale of Goods Act 1979, as this item is over 6 months old you will only qualify for a proportionate refund of the original purchase price. Therefore we are unable to issue a replacement as initially requested. If you send it back in 20 months time you won't get a full refund if faulty, unlike amazon.
Got it from Laptops Direct sadly.
£100 too much
Go for the 1070Ti it should have a better cooler.
If you got it from Amazon then return it to Amazon (use their Chat function to talk to a rep, don't bother trying to get a fault repaired). Gigabyte should have 2 years but obviously they will do whatever they can to save money and fob you off. This is why I always buy graphics cards from Amazon.
