You're over exaggerating. You have a very good CPU, and the upgrade which you speak of would have seen none, or at best, incredibly minuscule improvement in the performance. Bigger chance you'll get more out of your k edition by OC'ing instead of a buying a non k.
In general, I think it's bizarre we've come to people with as beastly rigs as yours, being concerned about not even being able to run it decently on just high settings. Either we're all blowing this way out of proportion by misinterpreting this, or CDPR will have some answering to do. Any self respecting developer who makes a PC title will make sure it's able to run at 60fps on at least next to highest settings without requiring a NASA computer. And let's be honest here for a minute, TW3 looks good, but not *that* good to warrant shit liking requiring 2x 980ti's or whatever just to make our way past 30 fps on high settings. Compare it to Ground Zeroes which, similar to TW3, has big open levels and looks great without being super duper amazing. But that manages to run amazingly at high frame rates on just half way decent rigs. I mean fuck, I saw one dude running it at 30 fps on a non gaming laptop.
Anyway, I'll be surprised and disappointed if TW3 can't manage to have a high fps on high-ish settings on great rigs, and as I said, I hope this is a mix of the game still being in the process of optimization or simply some sentences being taken out of context.
