Watch Dogs has finally been given a new release date (May 27), and perhaps PC players have been worried it would require a rather advanced machine to run, but there's no need to fear as Ubisoft have issued the minimum specs:
Intel Core 2 Quad Q8400 2.66Ghz or AMDPhenom II X4 940 3.0Ghz
6GB RAM
1024 VRAM DirectX 11 Shader 5.0
SCard: DirectX9
25 GB
Of course, as usual it may be more interesting to see what's recommended and what it takes to run it on ultra, but at least the minimum specs are reasonable.
