Question Specs for running Minecraft

[aircap1]

Interested in upgrading my computer. Either the fact it's old, the fact I know barely anything on cleaning computers, or the fact it just isn't good has minecraft running sluggish in general.
I'd like to be able to have shaders, a texture pack, and a decent render distance at 40-60fps.
I'm most likely going to be buying everything used.

Processor: AMD FX-4300 Quad Core Processor 3.80GHz
8GB installed RAM
GPU: Radeon RX 460
Motherboard: Gigabyte Technology Co GA-78LMT-S2 Version sex

On second look, I definitely need an upgrade on most things.
I'm looking for budget pc builds or budget pcs in general for great game quality
