I'm going to buy ultra gaming rig for ultimate gaming in which I will also install Skyrim Legendary E. and mod it with some ultra HD graphics,but I also want to get Windows 8.1 Pro 64-bit.but some guys told me that Skyrim ain't compatible with Windows 8.1.Is that true??But,before on Windows 8 I could play Skyrim perfectly fine.

One thread is enough; http://www.gamesas.com/topic/1503893-i-cant-believe-thisis-skyrim-compatible-with-windows-81/
