Lol. What are these "camps", "sides", you talk about? They are just graphics cards. Nobody signs a contract giving their soul away when they want to play video games. It's so funny reading these comments. People buy video cards based on benchmarks, prices and availability. Nothing else.
It does? There is no safe voltage and depends entirely on the CPU and how it's used. I would personally run mine at 1.425v and not worry at all about degradation. I might feel a little uneasy if the cpu was permanently stressed at 100% usage with benchmarks and folding but I don't do any of that. If I did I'd drop it to 1.3-1.4v.
