Is there a way to see a comparison of the three? Are they worth it? Is it complicated to overclock? From what i seen, you just use a program to overclock for free, so why not do it yourself? Does overclocking yourself void warranty or create issues? Can a 4070 ti oc beat a 4080?
1)Yes: have both on hand to test, otherwise it's not a fair comparison. Please be aware that these cards overclock themselves, so they're all technically overclocked.
2)'Worth' varies between users - that does include you, so there is no direct answer to this question.
3)It doesn't need to be. They overclock themselves, there's the option of using OC Scanner, or using one of the more complex methods out there.
4)Why not DIY-OC:
-more power and heat, neither of which Gpu Boost is a fan of and can potentially offset or nullify any real gains. Gpu Boost is built in and can't be disabled.
-GDDR6X memory has an error correction function, and if one goes too far on the memory clock, it'll actually worsen performance.
-the user's current psu might not be up to the task.
5)Technically, it does, but the manufacturer can't prove it. Issues? Yes: it's harder on the gpu's VRM and psu.
6)It physically can't.
