Juat looked at the ot headline and it actually says "best gpu card" and in that case its imo pretty simple the answer is 460. Without going into semantics

But for most part we are actually framing it the wrong way. Like whats is the fastest. Like we can ask what the fastest car is. But actually best card is a better way to do it.
Then comes the problem of anticipating how things is eg in a year or two. But imo its similar to the situation where benchmarking without eg minimums, frametime variance or subjective gameplay because argumenting its either to costly or subjective. We need to cross that line. But the info is spread all over. But its there.
Perhaps some of you guys should make some sort of meta review site collecting and presenting all this info. Make the framework.
