Oh but it is.Well that's not quite true though is it?
Are you saying the GTX 1070 was faulty?
Do you have any data to show it's more likely to snuff it than the next model along, or do you just not like it because it doesn't look "premium" like a Batmobile Edition (which it will perform similarly to anyway...)?
If it works as a GTX 1070, then it's a GTX 1070. If you want a GTX 1070 Strix OC or EVGA Hybrid, go and buy one and fit it yourself. Or spend the £80 premium on the GTX 1070 FTW2 model that's offered - which I can't recommend in terms of value.
Overclocking your GPU with PCS will invalidate the warranty (a policy that I disagree with, but it is what it is). And it's not like Pascal cards have all that much OC headroom. And blower cooler ones often end up OCing to similar levels to ones with more elaborate solutions anyway. And only a pretty small number of people will be looking to OC their GPUs.
PCS have used a range of 1070s. If you want a specific model for overclocking or any other reasons, get your own. It's not a problem to do so.
If your point is "I don't like this model, buyer beware that I don't like this model" then that's cool.
