The 1050 Ti works well with the i5-2400, and you might see better results with the i7-2600K thanks to its higher speed. The 2600K can be heavily customized, so if you're not doing overclocking, the improvements will be limited. You can run all games, but newer high-end titles may struggle on a 1050 Ti depending on their settings and resolution.
Your motherboard uses an Intel Core DP67BG chipset. For this setup, a good GPU choice would be one that matches its TDP and supports your desired performance level. Consider models like the RTX 3060 or RTX 3070 if you're looking for strong gaming or content creation capabilities.
Your motherboard isn't going to matter that much. There is no "best GPU" for a given motherboard.
Ensure your power supply can manage the load. Be aware the CPU may limit performance of the RX 570, particularly if you avoid overclocking. It will still outperform a 1050 Ti processor, and you retain the GPU option later if needed.
