We already heard that Watch Dogs will require a 64-bit OS and some beefy hardware, but now we have some specific hardware requirements for Ubisoft Montreal's open-world hacking [hopefully] masterpiece.
You'll need at a minimum, an Intel Core 2 Quad Q8400 at 2.6GHz, or AMD's Phenom II X4 940 at 3GHz. Ubisoft does recommend much higher specs, where it would like to see you use an Intel's Core i7-3770 running at 3.5GHz, or AMD's FX-8350 X8 processor clocked at 4GHz. When it comes to RAM, you'll need 6GB minimum, and for GPUs, Ubisoft's minimum requirements for Watch Dogs is an NVIDIA GeForce GX 460 or AMD Radeon HD 5770 with at least 1GB of VRAM.
When it comes to recommended GPUs, you'll need an NVIDIA GeForce GX 560 Ti or AMD's Radeon HD 7850. Storage wise, you better have over 25GB free to install Watch Dogs - not bad considering Titanfall requires a mammoth 48GB.
You can pre-order Watch Dogs through Steam right now, for $59.99 - it will be made available on May 27.
