Nah, gddr5 wasn't bad, it was nVidia's that made the mistake with adopting gddr4, they bought so much of it that they were putting out low range cards with 2GB vram just to get rid of it and they were still using gddr3 on high end cards. By the way, Maxwell GPUs have full dx12 support. Nvidia will support DX12 on every Fermi, Kepler, and Maxwell-class GPU. PS. Who is "everybody" ?! You mean AMD right? Intel is hardly going to put vram into CPU's And AMD still needs a faster card to get to gtx 980ti. Overclocking the memory on radeon GPUs doesn't yield much performance so i doubt they are having bandwidth issues, especially if we look at radeon 285 being faster than 280 with only 256bit bus on it. It's gcn that they improved and that yielded performance increase. But we will see.
