Maximum details, 2560x1600... I'd take the 7870 or the 580 over the 560 TI. Then, there's also if you're using a 3D and/or 120Hz... Then, even more performance would be needed. 120Hz or 3D would need something like a GTX 670 to get high enough FPS, maybe even more, like Radeon 7950 CF. Both 3D and 120Hz together would demand something like two GTX 680s in SLI, maybe even more.
