Please do not try to use a GPU to mine Bitcoin. Funds an asic that suits your needs!!
There is no need for warning this person because its not going to work, you make it sound like trying it will ruin the GPU instantly lol, the only way to get Bitcoin using GPU is getting paid in Bitcoin mining other altcoins like Ethereum, Ravencoin or Flux, another good example is Nicehash.That's what I mean! I can pay less for a GPU and use the free electricity on other algorithms getting paid in satoshi on nicehash...it is a way to stack sats with free energy and sounds me not bad...
