If you're planning on upgrading your graphics card in order to run SPM, be sure to get Nvidia. AMD's software is shit and its drivers don't work well with SPM at all.
If you have AMD, it's possible to make due but you'll spend a lot more time and still get worse performance than you would with Nvidia.
It's better to have 5 FPS and the best fucking grass you've ever seen than it is to have 60 FPS and bullshit.
