My rig is: GTX 570, i5 2500, 8gb ram.
Ran some tests, and locked it to 30 frames per second with RivaTuner. In the settings below I've ran into some occasional frame-rate drops to 27.
That's my settings:
Resolution: 1600x900
AA: TAA
AF: 16 samples
Texture: Ultra
Shadow Quality: Ultra
Shadow Distance: Medium
Decal Quantity: Ultra
Lighting Quality: Ultra
Godrays Quality: Medium
DoF: Bokeh
AO: SSAO
View Distance: Everything maxed out, except for "Object Detail Fade" wich is set on High.
Screen Space Reflections: Checked
Wetness: Checked
Rain Occlusion: Checked
Motion Blur: Checked
Lens Flare: Checked
For those wondering if they should get the console or PC version, I'd definitely recommend the PC version for anyone with specs similar to mine.
