Most of what i look for is future proof Graphic PCIe 5.0, which i have already on this motherboard, and m.2. Gen5. Don't use anything more than USB3, and have a CAT5 connection to the internet, so no need for WIFI 6E or 7. Those are the two main things i look for in motherboards Graphic/M.2 drives at Gen5.
Memory overclocking would be nice, but all you need is either 6000Mhz for 7000 series or what is it 6400Mhz for 9000 series AMD. Unless you are talking about tightening up the timings to Cas20's. Also memory is really cheap right now too.
You’d probably be fine with an x670/b650 board then.
In terms of memory overclocking I more meant better 2:1 clocking for higher frequencies 8000+. Huge unknown atm until people have their hands on a zen5 part and or in combination with 800 series boards.
Personally I’d wait for the newer boards, but I’m in no rush to buy anything.
