I am looking to upgrade my core i5 4690k system as I am running into I/O issues with the old USB bus system and the mobo I have presently only has a single pci-x4 slot and I'll need another to get four additional dedicated USB channels with a card for cameras or a mobo which can accommodate 4 dedicated USB channels itself. I am not a gamer but do video editing and a lot of design work and streaming so multithreading is important. I am looking to go back to AMD now that they are on top again and the Ryzen 7 3700X looks the most appealing. I have a EVGA GeForce RTX 2060 SC Ultra and Samsung Evo 860s so I am solid on that front. What would be a good stable mobo with some overclocking abilities, no need for wifi, and a solid 32GBs of RAM to go with it? I do enjoy overclocking a small amount while maintaining stability. My case is 15 years old so updating that would be a good thing as well but a lower priority. What would be the best bang for the buck with this kind of build? Thank you!
