Grr I thought we already covered this in the other thread

There is little point in dual if you want to be set for the future. People saying you don't need more than a dual (even with Hyperthreading) is like all the people that said "there are no multithreaded games, so just get the fastest single core available". Then people bought FX-55's and Athlon64 4000+'s and overclocked them like crazy...and then Oblivion came out and the people who put that money towards a 4800+ came out ahead.
Same will happen with Dual/Quad as developers get better at multithreading.
This is not the right comparison. People buying i3 or LGA1156 pentiums are buying ~$100ish processors. 4000+ and FX55s were nowhere near $100. You want to compare people who bought a 3000+ or 3200+ and overclocked like crazy.
When you buy <$100-150 processors you don't risk a whole lot in terms of the future. You upgrade in a couple years to the next $100-150 processor.
You don't buy for the future at all in that price range. You get performance now from the overclocking, then you buy again in 2 years. I mean what's a i5 750 gonna be like in 2 years? Whatever $100-125 processor that is out then is going to roast it and people are gonna want to upgrade even if they have an i7 750.
Buying computer hardware "for the future" is something hardware manufacturers bank on. It's like buying insurance. The insurance companies are sure to come out on top. Or going to Vegas, the house always wins on average.
Buy for the here and now and buy on the value end of the spectrum and you're not very invested, so there's very little issue if you end up making a mistake. It's not like a 4+GHz Clarkdale is going to be slow in any real world applications now. If you were using one of the applications it were slow in extensively (something that benefited significantly from quad core right now,) then you wouldn't even be looking at buying a clarkdale anyway.
I'm guessing the people upgrading to an i3 (more than just to play with it some and then sell it on FS/FT) are going to have been on an e7200 max. And this proc is the next e7200. same price point, similar OC capability (relative to stock speed), just higher numbers that come from 2 years newer tech.
