Iron replacement, what to look for?

Question

Java

I got interested in Java, in particular Android dev, and realized that there was clearly not enough hardware performance. Therefore, the question arose about the upgrade. What you should pay attention to when choosing a processor, mat. boards and memory? AMD or Intel, DDR3 or DDR4?
OS win 7, 10 or linux?
Thank you.

Answer 1

AMD or Intel

If you need not the minimum performance, then Intel.

DDR3 or DDR4

DDR4 is much newer. More upgrade options, and DDR3 usually has a low RAM limit, and you might want more.

OS win 7, 10 or linux?

minix. Are you a troll and don't know the name of the OS you like to use?

What you should pay attention to when choosing a processor, mat. boards and memory?

On an SSD.
Android Studio will be very slow without it.

Answer 2

You can add RAM to start. But so that it doesn’t work out that later you want to change the board and the new RAM will not work.

Answer 3

What you should pay attention to

On what the load is higher when working with the IDE, it is this part that needs to be upgraded in the first place
