Post title pretty much asks the question. My current PC is a i7-6700K on Gigabyte Z170X Gaming 5 board with a Gigabyte GTX1070 GPU. I would probably see performance gains with a RTX3070. But is the CPU and motherboard so old that the limitations outweigh the gains? I just don't feel like spending $2K+ on building another rig. PSU is 650W and have 16GB of DDR4-3200 RAM and Samsung 970 EVO 1 TB NVMe SSD.
