Are the new intel models (i5-4670K) not relevant for testing?
Already answered, but no, they're pricier than Ivy Bridge with marginal gains at best. For the money, Ivy Bridge is still the best gaming CPU.

What about a Xeon E3 1230 V2. LGA 1155, 3.3Ghz w/3.7 boost, 8MB L3 Cache, 8 threads, 69W, for the price of a 3570K ($225 - or $200 if you're near a Microcenter).
For someone who doesn't overclock, who also does 3D graphics or other CPU intensive productivity work, and for latest titles optimized for higher threads, it seems like this is a great gaming value.
I've recommended the Xeons on a few builds as they have very interesting properties. But again, this is about
gaming CPUs. Games don't utilize the extra L3 or threads. You're paying $50 over the 3350P for no improved gaming performance. Though I agree, for the pro-sumer that more than dabbles in professional apps, that Xeon is tough to beat.

There is no way I would pick an i3 over an FX 6300. The FX 8320 is a better value than an i5 3350p. I wouldn't consider an Intel chip under an i5 3570k for a gaming rig at this point.
Blanket statements like these are extremely ignorant. Both Intel chips have vastly better power and thermal envelopes. If those things are important to you ( say a small form factor build with limited cooling and power, ) Intel wins. They're also much more efficient in lightly-threaded apps, like the vast majority of applications now. These two don't overclock, but they're more than adequate for most anything you throw at them at stock clocks. If you're constantly running more threads, don't care about heat and power, and have OCing room, then the FX chips are a good way to go and save considerable money.

You would really buy an old Ivy Bridge CPU instead of one of the new Haswell processors? There must be some advantage to the new chips: faster at stock (most people don't overclock), better integrated graphics (for people who mostly use the machine for productivity, but also do some light gaming like LoL).
Haswell does have a small IPC improvement and supports some new instruction sets ( IIRC on the latter. ) However, both the chips and mboards are more expensive than their IB counterparts.
The cheapest Haswell right now is still ~$190 whereas you can get a nice casual i3 for $120. Add in a $20 difference between 1155 and 1150 mboards and you can get an IB i3 + 7750 for the same price as a Haswell i5 alone. The former would be a much better casual gaming system.
Now if you're building a higher-end system right now and you're not considering anything below an i5, then Haswell makes a lot more sense since that price difference doesn't mean as much when you're spending extra cash on GPUs and a beefier PSU.
