Hello everyone, this is going to be my first time building a PC that is used for work/gaming. im going for a micro ATX case and i was wondering the best motherboard that would be used for Ryzen 5 3600x and a Rx 5700 XT i have been thinking about the following motherboards (under 100$ US dollars) : 1- GIGABYTE B450 AORUS M 2 - ASrock b450m pro4 3 - msi ( not sure which one since there are too many) much help and recommendations would be very appreciated, this is the last step im taking to order the pc parts.

here is my build, Crucial Ballistix Sport LT 3200 MHz DDR4 DRAM Desktop Gaming Memory Kit 16GB ( RAM ) ASRock MicroATX Motherboard (B450M PRO4) (motherboard) AMD Ryzen 5 3600X 6-Core (processor) Seasonic FOCUS 550 Gold SSR-550FM 550W (power supply) AMD Radeon RX 5700 XT ( G.card) WD Blue 1TB PC Hard Drive - 7200 RPM Class, SATA 6 Gb/s, 64 MB Cache (HDD) SanDisk SSD PLUS 240GB Internal SSD - SATA III 6 Gb/s (SSD) Total : USD 1,018.88 i already have a case and a monitor 1080p. this is my first PC build ever and im trying to keep it around 1000 US Dollar including the shipping fee, all from amazon. what i will be doing on this machine is to play games and do some work on film editing, modeling and Auto cad inventor. i would say that i do play lots of games so i would still like high performance running but, im a cheap ass student who had a shitty laptop for 9 years now and im not really sure about AMD graphic cards. please help
