What computer specs are necessary? I've got a upper middle class machine, but definitely not a 4K graphics gamer.
Dual Core CPU Intel: Core2 Duo 2.4Ghz or AMD: Phenom X2
8GB of RAM
DirectX 11 capable GPU: NVidia Geforce GTX 460 or AMD Radeon HD 5850
Recommended system requirements: Windows 7 or 8 64-bit
Quad core CPU: i5 2500, i7 2600, 2700
DirectX 11 capable GPU: GTX 670 or greater
And for a smooth experience at Maximum settings at 1080p, a R9 290x, GTX 780 (or 970) will be required (a GTX 770/680/R9 280x will likely therefore likely achieve high comfortably). For a decent 4K experience, a pair of mid-high end cards (680/770 7970/280x or better) or a newer high end card (GTX 980 Ti or AMD Fiji etc) will be required.
