I would suggest B450 TOMAHAWK MAX | Motherboard | MSI Global instead. Gigabyte has been lagging with BIOS since the beginning and can't be 100% sure (unless you check with seller) that it comes with full 3rd gen Ryzen compatible BIOS. MSI Max MBs come with one for sure and have an option to update BIOS even without any CPU. 5450 is woefully inadequate nowadays. Any newer games and high res is out of question. Not even sure it would work with this setup.
Unless you desperately need 6 cores, R5 3400g may be better option, it even comes with GPU waaay better than 5450.
