Hi I am currently a bioengineering masters student and I have a bachelors degree in molecular biology and genetics. I have been thinking of getting into bioinformatics and data science and my problem is that I have a 9 year old i7-4700hq, 16 gb ram (at 1600 mhz) laptop and whenever I try to watch a course and try them sumilatinously noise cracking, freezing starts . This may not be the right place for this but if I buy something new what kind of processor and ram should I get ?
