I'm getting a Rx 470/570(Depending on my budget and the price). I got a Xeon E3 1220 CPU and i don't really think it's a very powerful cpu so I'm also thinking of upgrading it first. I'm just aiming for a 60 hz 1080p med-high settings experience so it's fine if it'll just bottleneck a little bit. So should i get the gpu or not?
