If I remember correctly, running a 3080 10GB in PCIe 4.0 yields >5% performance average in gaming benchmarks compared to running it in PCIe 3.0. You could probably argue that you should just settle and not take the 5%, but when you are buying in at such a price point, you are likely concerned with 5% differences. There are also higher end SKUs such as the 3090Ti where that performance gap is likely larger.
