i am looking to get an i5 8600k/9600k and was wondering what would be the best z370/90 motherboard for overclocking under £160.
As far as overclocking goes, definitely the MSI Z370 A-Pro, the MOST inexpensive and also a beast at overclocking.
If you want both low price and overclocking potential, nothing can beat this board.
