The titian line in not a purely gaming GPU! The higher price comes for leveraging it's GPGPU CUDA technology. It's like buying a server hardware and complaining it doesn't run your games and well as an i7 which costs less. Game enthusiasts always ruin hardware news with their one golden spec, the frames per second! "That said it’s clear from NVIDIA’s presentations and discussions with the company that they intend it to be a compute product first and foremost (a fate similar to GTX Titan Black), in which case this is going to be the single most powerful CUDA card NVIDIA has ever released. NVIDIA’s Kepler compute products have been received very well by buyers so far, including the previous Titan cards, so there’s ample evidence that this will continue with GTX Titan Z. At the end of the day the roughly 2.66 TFLOPS of double precision performance on a single card (more than some low-end supercomputers, we hear) is going to be a big deal, especially for users invested in NVIDIA’s CUDA ecosystem." - AnandTech
