Wow, this thread's been dredged up from the graveyard!
I have a Sapphire Pulse 6700XT in storage three feet to my left. It's a fine card that's just one step up the pricing ladder from the cheapest model you can buy and whilst It only overclocks to about 2650MHz, overclocking is pointless these days. If you achieve 10% higher clocks, you get 5% more performance, which is small enough to be irrelevant if you actually need that performance (j.e. you're trying to reach playable framerates from unplayable framerates). The penalty for that overclock is 30% more power draw, which is expensive in 2023, and even if the graphics card's cooler is overbuilt enough to remain quiet (which you pay a poor-value premium for) the rest of your PC cooling will have to deal with that additional heat load, likely negating the quiet GPU cooler anyway.
Always buy the best-quality cooler/manufacturing of the MSRP or base-priced models. If you can afford the factory OC flagship version of a GPU, you aren't far off being able to afford the next GPU model up, and you can underclock that for low noise and better efficiency that will still likely beat the flagship variant of the GPU model below it. In this case, the Strix and Nitro 6700XT have never been priced significantly lower than the entry level 6800 cards, which all run circles around any 6700XT, no matter how overclocked they are.
