EA Releases Crysis 3 Specs
First, the minimum specifications: to play the game at all without it degenerating into a slideshow of pretty snapshots, you'll need a DirectX 11-capable graphics card with at least 1GB of video RAM such as the Nvidia GeForce GTS 450 or the AMD Radeon HD 5770, a dual-core CPU of equal or better performance than Intel's Core 2 Duo E6600 or AMD's Athlon64 X2 5200+ and at least 2GB of memory. Those gaming on Vista, rather than Windows 7 or 8, will need to have at least 3GB, EA recommends.
If you'd like things to look a little prettier, the recommended specifications bump things up to 4GB of RAM, a quad-core chip of Intel Core i3-530 or AMD Phenom II X2 565 equivalence, and an Nvidia GeForce GTX 560 or AMD Radeon HD 5870 or better. Finally, if you want to really push the boat out and turn the graphic settings up high, you'll need 8GB of RAM, an Intel Core i7-2600K or AMD FX 4150 or better, and an Nvidia GeForce GTX 680 or AMD Radeon HD 7970 or better.
