Hi there i want to learn data science online either on coursera or edx where i will've to finish a capstone project at the end of the course. But my laptop died on me. I am confused about whether i should buy a laptop or a desktop and of what configuration.. i have a very limited budget of 30000 BDT or 400 USD. i was told by some guys that i should get a quad core cpu to work on Data Science. What will be the best configuration of a desktop or laptop for me to learn data science and building a portfolio on my learning. I will've to be able to work on small data projects to earn to upgrade my system later. I found some shops who sell some project used (officialy) laptops exported from abroad. They are affordable but of very older generations. Can i go with an i5 4th or i7 2nd/3rd generation laptop with 4/8 gb ddr3 ram & 500gb hdd without any dedicated gpu on it?? can i get an i3 8th generation 8100/8300 quad core desktop (including main board, 8gb ddr4 ram, monitor& everything else) within this budget?? Which path should i choose?? Or it would be better if i go for an amd quadcore desktop with amd a8 7670 cpu?? Any reply is highly appreciated
