There is a potential part Compatibility problem will it actually ba a problem or will it be fine?
yes it would be a problem, the cpu wont work till you do the bios update
I advise a z270 motherboard.
The current motherboard needs to run another cpu first, update the motherboard, and then you can use your cpu.
Which specific motherboard would you recommend?
I find it difficult to recommend something for others. But mine asus z270e arrived yesterday, and i like it :)
