According to Apple, the entry-level 21.5-inch iMac features a 2.7GHz quad-core Intel Core i5 processor and new Iris Pro integrated graphics. The high-end 21.5-inch model and both 27-inch models feature quad-core Intel Core i5 processors up to 3.4GHz and NVIDIA GeForce 700 series graphics with twice the video memory and up to 40 percent faster performance than the previous generation.
My fully maxed out machine is still $3400. Of course, that’s the same price as it was for the last version, with lesser specs, and half the ram. Still an expensive bit of kit, but a damn nice bit of kit.
