The current price difference on Amazon is $5. But the 7700X doesn't include a cooler. If you're not planning to use the AMD cooler, may as well pay an extra $5 and get a processor that binned better (probably), not have the extra cooler, and you can fiddle with voltage and TDP/power limits from there.
Depending on your cooling, having a 100Mhz higher max clock could be worth $5.
