top-tier LGA 1150 CPU options
The 1150 timeframe is quite distant and upgrading within that range isn't advisable. Consider moving to 1151, 1200, or 1700 if you're using Intel processors.
You could choose a Haswell i7 such as the 4770, 4790, 4770K or 4790i5. That would boost your performance by a few percentage points over the RX 570. I remember you mentioned 470, that's equivalent. However, many people are interested in those CPUs, which I don't think is justified. A better option would be a modern i5 10400f on a B560 board with 16GB DDR4—this would provide a substantial upgrade.
Yes, an Intel Xeon E3-1230V3 would be suitable for around fifty dollars.
It's the i7 4770 model without the built-in graphics chip, running at lower speeds. When fewer than four threads are needed, the i5 performs better than the Xeon.
