That gap between synthetic scores and real games is exactly why I stopped looking at 3DMark first. Lately I check the
H2Bench GPU benchmarks, because their FPS Lab collects runs from regular players through a small Windows app, and each result needs video proof before it's approved. You see average FPS, 1% lows, the CPU it was paired with, resolution and preset. For real-world expectations that's more honest than a lab bench with a top-end CPU. Fair warning though: the number of measured runs is still modest, so your exact card and game may not be there yet. I use it as a second opinion next to a couple of reviewers I still trust. In that case their spec comparisons and score are still useful as a baseline.
