You're always taking things out of context (Just like you're doing now, which is why I struggle to take you seriously)
No one's saying they don't run "fine" (Ignoring the fact how subjective saying something is running fine is) but factually, it is and will get bottlenecked (How much vastly depends on the games and resolution)
The reason I ignore Alex, as frankly what he says flys in the face of next to everyone else who have used the set ups (Like now, you've got Panos, Aveneged etc, all using set ups, all noticing differences, instead you go to Alex, who sees "No difference", even on WoW, which will see a difference, regardless of how many time he says they're the same FPS) but what's the point in bringing this up? It'll just get discounted as everything else does, wouldn't even say I'm spouting Panos, he's posted in this thread, his experience, it's on topic and you've said you believe his opinion (Which again, makes no sense, because he's mentioned about bottlenecking a 79XX Crossfire, but given your response to Beasty means you don't believe it at all)
No one says you get a bad experience with FX83 point blank (Well maybe Boomstick, but I've had him on ignore for about a year anyway

), no one at all, it's only your twisting that means it seem that way.
I mean hell, given that little snippet in your sig, it's silly to even try and take my comments out of context, I'm a big fan of the value they represent, they've changed the scope on what you can get on a budget CPU wise. But that doesn't mean I'm going to pretend they're more than they are, (And I've been saying how good price/performance it is since it launched in October 2012,)
I rarely ever mention the i7 in comparison to the FX, unless it's very high end GPU set ups (Because the i5 doesn't cut it when we're getting to the heavier hitters which are more threaded, which need that extra GPU grunt really, even though it's only a small amount of games, it may/should grow in future)
Whereas you seem to hate the i5, and refuse to suggest it over an FX83 point blank (While calling me an Intel preacher, this that and the other) you completely flat out ignore just how many times I'm happy to suggest AMD rigs, here's one I did earlier

I literally have no bias, perhaps that's why I'm so outspoken, because I can't understand brand loyality, you go where the numbers take you, that's what I care about, the pure numbers, not what sticker it has on it.
As for "owning" an FX83, I haven't, but I've used an FX83 and an FX63 in builds I've done.
And you can't really downplay Thuban, given how Humbug's just had an 1100T (Still lower clocked than I had my Thuban at) beating a 4.6GHZ FX6300 in Cinebench (FPU performance) Highly clocked Thuban chips will still ride with the highest end of AMD stuff in far, far more games than they don't.
OP's mentioned his i7 4770K and board is arriving Tuesday, so we'll see if he notices differences.
End of the day, I have you on ignore for a reason, and should stop reading your comments, it's just full of contradictions and u-turns and your "opinion" changing like the wind in what you say (Or at least it seems that, one minute you're saying you can't see the FX83 bottlenecking a 7990 and we're all obviously lunactics, then in the first sentence you're saying you need something more than an FX83 to get the most out of an R9 290X, which has less grunt than the 7990. Which then doesn't make sense, as you never see a point of the i5 over the FX83, so that'd mean you'd be pimping out the i7 with the R9 290X, as the i5 is "Not worth it" over the FX83 as you've said many a time......)
