by Nick-Farrell (Feb, 2014)This graphics core incorporates several new features that allow it to improve energy efficiency by 40 percent - essentially giving longer battery life for the same performance or improving performance when you really need it," Kolar wrote.
by Ryan-Smith (Sep, 2014)From a performance perspective Apple is promising 25% faster CPU performance than A7.

It is designed to show off GameWorks technologies, such as volumetric lighting and HBAO+, more heavily than Bethesda did with the base game.
If you're wondering why NVIDIA has a game development studio, they are mostly responsible for bringing content from the PC to their Shield devices, such as Half-Life 2 and Portal.

If it's for both the GPU and display, I would still wait.
If you can wait it out, I would really suggest you do as it's not only going to be great when it comes to new GPUs - but the older video cards should drop in price, too.

My current system is a 2500k and GTX 670, so the upgrade bug is biting hard, but i can also wait, as the Rift and the HTC Vibe wont really be widely available until the Summer.
On the other hand, if you needed to (or anyone else reading this) buy something now, then the price drop on the R9 Nano has been a great thing, and good timing.

The latter model works better in multi-core environments, and it aligns with GPU compute APIs, but the former is easier to port OpenGL and DirectX 11 applications to.
Even though OpenGL on Mac OSX is not considered to be on par with its Linux counterparts, which is probably due to the driver situation until recently, it pulls ahead of Metal in many situations.
