The flagship Radeon R9 290X delivers performance similar to the GTX 970 in most cases, includes 4GB to 8GB of memory with a higher 512-bit memory bus (as opposed to the GTX 970's 256-bit bus), and can often be found for less than the $330 and up Nvidia card — and sometimes far less if you can find juicy rebates. That makes the Radeon better suited for high situations that require more memory — again, very high resolutions and/or cranked anti-aliasing settings — but AMD's cards are far less energy efficient than Nvidia's. Decisions, decisions.
And surprise! There's already a Change.org petition by upset GTX 970 buyers demanding a refund from Nvidia.
