hi mate
I have limited laptop knowledge but if running on a budget for rekordbox you could get one of these for windows
I own both. The screen on the Macbook is far better and brighter. Should do you for another 3-5 years yet.
If not choosing those just make sure they 1) have an SSD and 2) have 16gb or more of RAM.
(They will run on 8gb but we’re entering territory with software now where thats pushing it)
