evga has the best customer service and warranty by far. any one of their models will make you happy. if you want to feel secure having extreme quality vrms/mosfets, a highly binned chip and no crappy elpida memory, and the best voltage controller available all on a wide body custom pcb with much larger fans and thus, quieter while providing the best possible air cooling compared to any other model(with the lightning being the only other possible contender)... get the classified.
