Those lucky enough to have pre-ordered the Nvidia GeForce RTX 2080 Ti or RTX 2080 back when they were announced should have received their graphics card(s) by now. However, if you were (intelligently) waiting for benchmark results to come in from reputable technology review outlets, your wait is over.

We’ve thoroughly tested both of these new graphics cards in some of the latest games and performance benchmarks, and the results are both exciting and interesting. As you can see by the tests, these cards are for some reason stronger in 4K and HDR game performance than in straight 1080p.
