Or all the cards you have available are LHRs version?
If you can answer this and the price, we can help you better
It's almost impossible to find non lhr cards nowadays in my country, only used
I hope they are not LHR but it is not a big disadvantage anymore compared to non LHR cards.A good RTX 3080 with the perfect tuning without overclocking it to much makes like 90-93 Mhsh while the 3080 LHR thanks to many miners unlocking a huge chunk of the LHR makes like 68-72 Mhsh from what I have seen and I don't see that much of a difference,even the RTX 3080 LHR is good for mining (of course it is better to use non LHR cards) but when you cannot find 3080 non LHR going for the LHR version if you can find them I would say is not that a bad option.They will consume a bit more power because of the unlock needed but in the end having six RTX 3080 cards,LHR or not is great for mining right now.I consider them the second best cards beside RTX 3090 which is the absolute king.
I know six of such cards if LHR offer like 100 Mhsh less but as I said still a good option if you cannot find non LHR cards.
