The thing is, if people believe something to be incorrect, doesn't mean it is. Plenty of other people then and since have shown memory usage to exceed the limits of some cards at high resulution in certain games.
Well to be fair, I don't believe some people truly believe what they post. After all, trolling is one of those things defined by intent. If someone comes onto OcUK with the intention of posting drivel believing it to be true, that isn't trolling, it's just stupidity. Trolls are those who post simply to wind others up.
So what do you do with those who come on to troll, but hide behind the excuse of "oh, it's my opinion"?
