The RX570 probably has some life left, but the i7 930 is rather old. From before the big jump Intel made with Sandy Bridge.
I fear you'll need to upgrade your platform. New i5 or Ryzen 5 should be a massive jump, but you'll need CPU, MoBo and RAM.
Second hand market might be an option, but that depends on where you live, and Intel tends to be overpriced, so don't overpay.
