Nvidia recently (at international PC celebration Game 24) announced a pair of high-end GPUs. These avail of energy-efficient, VR designed Maxwell architecture. They go by the names, GeForce GTX 980 and GeForce GTX 970. They are not expected to be cheap.
Why did Nvidia opt for Maxwell architecture? According to Nvidia, their new Multi-Frame Sampled Anti-Aliasing tech can generate a 4x multisample anti-aliasing image at 2x MSAA speeds.
Which is probably pretty impressive.
If you speak that particular language.
Additionally, it can produce 4K images and downscale them to native resolutions, which is handy.
Via press release, Tim Sweeney, founder and CEO at Epic Games said,
"We built Unreal Engine 4 using Nvidia's Kepler architecture but the GTX 980 and 970 GPUs, based on the new Maxwell architecture, are the most powerful, efficient GPUs for creating scenes of unprecedented detail across PC and VR experiences right now… Our developers are pushing the graphical high end with Maxwell GPUs."
