Could an 8 core amd processor work? I know the cores aren't as "strong" but would it be better than anything I could get at the price

Whoever told you that is bullshit. A core is a core. I use an 8-core 5.1ghz machine with a samsung 960 pro NVMe hard disk and 32GB of overclocked memory for my dev machine, on 5 monitors (see image)

Do I need a good gpu and how much ram, 16?

You don't need a gpu for development. I'm using a Radeon RX480 Gaming X (4GB) on my machine and it works fine. I chose this card specifically so I could run all 5 monitors. I game on 3 of the monitors (at once), and I can pull solid 70fps.

Now before we get into the 200fps debate, I want to lay down some facts. Your eyes don't see that high of a frame rate to begin with, but unless you have a VERY EXPENSIVE monitor, it runs at 60Hz, meaning the monitor only displays 60fps. So, as long as your graphics card can pump out 60fps you're good. I usually cap my games at 62fps just for good measure. Extra frames are just wasted CPU time.
