Golden samples are bread and butter of the industry, journo's always get a working board, the best silicon etc. You can't stop that, because no one is going to buy everything. The good thing about OC % is that it's catalogued by the community en-mass anyway, rather than by any the small number of tech sites saying 'we achieved %' on our sample. But it's not just about GS products - a majority of the manual work on positioning the product, providing materials that conveys the story well, getting product to reviewers in good time with software that works: being well prepared and having solid business PR process. If it makes your life easier, it affects the sentiment. That's only amplified in user reviews on Amazon etc, which is were ~80% of buying opinions are created. And at the end of the day you never want to read 100% sanitized benchmarks, because reviews are still a form of entertainment, so you go to read opinion derived from a feeling just as much. I'll admit Nvidia constantly does well in PR and branding machine, while AMD have historically had piss poor PR and not a strong or cohesive corporate marketing team. Again, in a sanitized world of technical achievement divorced of product names and such, it shouldn't matter, but it really does.
