My zotac geforce gtx 560ti amp edition is a reference model aswell but it didnt cost alot of money and what mattered for me was that their RMA service will still hold even if you watercool your card.. id gladly pay a little more for that and not to mention i can clock higher due to amp edition and watercool.. trust me i see the benefit of saving money ive just never seen a cheap card throw heavy points in bench but id gladly change my view on this if im wrong
