i have a 970, overclocked it to 1500mhz boost clock and 8000mhz memory. Runs like a champ for 1080p gaming. DSR for playing those old games is great plus also. But seriously, why the fuck do we have to rely so much on the graphics card memory? Why can't the PCI-Express bus have more bandwidth so the GFX card can more efficiently use system memory without the limitation of the PCI-express bus? But i guess we still need something like DDR4 to have better bandwidth to make that even relevant.
