Destructoid and the recommended specs are kinda beefy. Not Crysis 2 at max settings beefy, but you'll need a GeForce GTX 400 series or better, or ATI Radeon HD5000 series or better graphics card, and a quad core processor under the hood -- you know, if you're looking to really soak in the visual symphony that is watching a man in a feathered hat kill a helpless citizen on the streets of Steelport with a gigantic dildo bat. The required specs are a bit more forgiving.
On top of that, Volition also posted about some specific PC features over on the Saints Row site, including "AMD Eyefinity support, DX9, DX10, and DX11 support, Crossfire enabled, SLI enabled, advanced depth of field, reflections, and ambient occlusion quality, and, of course, God Rays." Perhaps the platform's best feature, however, is the Saints Video Record Mode, which allows you to save specific gameplay clips and upload them to your preferred video hosting service. Or we guess you could just hold on to the clips as a personal, secret reminder of that one time you did a barrel roll in your Mercedes through a crowd of people. Entirely up to you.
Saints Row: The Third launches on November 15 on PC, Xbox 360 and PS3.
