If I get an AMD processor and an Nvidia graphics card. Would it matter if i got either a gsync or a freesync monitor?
Yes, all monitors are compatible with all devices. If you have an NVIDIA graphics card with a FreeSync monitor, it will just function like a normal non-FreeSync monitor, and vice versa.
CPU brand doesn't affect FreeSync/G-Sync compatibility, only the graphics card does.
