but they're publishing Infinite on Steam. You do need Steam on the PC to play it, but it's actually gaming crack in the form of software, so you'll be happy with it. Plenty of demos and freebies, and the sales are frequent and oh so tempting. Steam is now also on linux if you use that OS, and you don't have to repurchase any of your Windows games when they're released on linux. Aren't they nice?
As for system requirements, I have an AMD Phenom 2 Black CPU, 8Gb of Corsair RAM, and a NV GTX 560 running Windows 8 Pro 64-bit, and I was able to max out the quality, including the special DX11 shaders and alternate post processing method, and run the game at a consistent 60fps at 1366x768 (1920x1080 was a little choppy on my rig at max quality).
Play it on the biggest screen you can use. It's totally dazzling on a 50" TV
