Don't even worry about it. I have Windows 8.1 (64-bit) running fine on two old Dell Optiplex 780 workstations with Core2 Quad Q9400 processors, using default drivers. One of those was a clean install. The other was originally set up as a Win7 Home (64-bit) install on a Socket 939 AMD board with an Nvidia chipset and ATi graphics, upgraded in place to Win8 64-bit, and later the hard drive was moved into the Optiplex without moving the GPU over. Windows reconfigured itself for the new hardware in about five minutes. It was then upgraded to Win8.1 and is running smoothly using the onboard video.
If it survived that, it should be absolutely fine with anything new enough to support Core iX series processors.
