Can someone explain to me what the difference between a 1070

>>59492948
More expensive - more overclock potencial

brands rework the base gpu.
they either change components (usually with better ones, so a little better memory or better cooling, 2 fans instead of one, additional ports to output, etc) and also OC the cards.
typically, these changes are not worth 70 burgers, the increase of power of the card is still minimal, it's just quality of life improvements.

>>59493111
You said typically. Are there are cases in which it's worth seventy bucks?

>>59493111
Oh, and thank you, by the way.

not him, but it also depends on how much you value $70

More expensive cards are any combination of these:
-Factory Overclock
-Better Cooling
-Higher Quality Components
-Non reference design (redesigned power delivery etc)
-Better Binning
