Yes this board is a much better option than what OP mentioned, but do note this board requires DDR5 and those are still pricey when compared to DDR4, apart from that hope you’ll enjoy your new build ☺️👍🏻🤞🏻

If your bios is 1202 version or higher dated June then it will support 14th gen CPU, I am running 14700KF with that exact same board updated with new bios dated October.

I think in B760M there is no undervolt option like Z series boards, so it’s doubtful you can lower it, you can only adjust PL1 and PL2 to a certain limit so that system uses less watts and lower temperatures, instead of doing anything just try to run games and see how the performances are, synthetic benchmarks are kinda pointless to determine gaming performance unless you like doing work with that CPU and then it matters a bit.try any in game benchmarks and also note the 1% lows and 0.1% lows too and those are important in gaming along with average framerates
