If you want to do so, you might want to also consider 2400g, with the right ram, it’s quite close to a 1500x + rx550
And you can throw in a more powerful video card sometime down the road. Rx560 ‘s price is still a bit inflated. With 2400g if you upgrade with a dgpu, you still ends up with 1500x which is 4c8t cpu.
I5 8400 is the same story, but the graphics are much worse than vega11, yet featuring a mooch more power cpu.
