I am a Data Science Student and looking to change my system, macbook pro m3 is currently at $1449 at best buy. Previously I was planning to buy m2 15”(16gigs,512) but the price are same. So, for the same price if I am getting new m3 chip, is it better to buy m3? Is 8gigs enough? Or should I spend more and buy 18gigs m3 pro? Is 8gigs enough for data science related programs? Help me out
