I don't miss the wildly fluctuating FPS in some games on the FX83## that the Intel completely cured.
But yes, i do miss doing multiple heavy tasks at the same time, no longer having the FX83## makes you realise just how good it was at that sort of work, you can ask it, "do this, and now this and this, and a bit of this", it just turns round and says "ah ##### no problem" and the system is still just as smooth and responsive as it is at idle, ask the Intel "do this and this" its response is " what? you're having a laugh, i can't do that and that at the same time, WTF is wrong with you?
And its not just down to how many cores it has, there is far more to it.
