Gaming parts from US for UK faming pc
Can someone please help me out.. Im building my first pc. I would really appreciate some input. Can I get parts from US for my rig if I bought my mobo from UK. Say a new 470 or 580 a friend said they would help me out with by shipping it over.. He also is sending some used ram. Will it go into a msi b350 gaming pro mobo I got on a uk site with 600watt power supply. I am also getting a freesync 144hz monitor in the uk will that be a issue? I understand this is a silly question but I have no experience. Thanks!
