I5-3450 VS. 2500K

Hello all!
I am planning this build of mine, so I need a definite answer to which processor is better between them, AT STOCK. Yes, I have no intention of over-clocking at all, and I'm just talking raw-performance-wise.

I would certainly get an i5-3450 if its performance >= an i5 2500K, because of the fact that I already have a PCIe 3 board with the AMD 7870.
Any help is appreciated!

More about : 3450 2500k

i5-2500k at stock clocks will outperform the 3450.
Another reason:
Simply because YOU CAN overclock. Keep in mind every 18 months intel releases a new processor, so you can bump the cpu up by a few hundred mhz and be on par! But with the 3450, you get a locked multiplier and can't overclock.

The Passmark bench (which is the only one available at the moment comparing both) shows the 3450 surpassing the 2500K, and by quite a good amount! Well, I am certain that I will not overclock, I think that the gains of haveing a PCIe 3 system weighs more than OC'ing, or am I wrong?

I just want to know if there are other benchmarks available, because I seriously tried all links on Google.
And albeit being locked, the i5 3450 can still manage a 400MHz overclock.

First of all, PASSMARK is fake and inaccurate. Many of the scores there are completely false, for an example:
An FX6200 outperforming an i7-950!

^ +1 Passmark is pretty much useless.

Great. Now I can't base my search on anything :'( 
Well then, I'll have to see when more benchmarks appear...

Why are there no benchmarks available for the 3450? Would have thought toms and anandtech would have been all over the icy bridge.

With the 3rd generation Intel® Core™ processors you are going to see about a 6% improvement in performance without using the IGP over the 2nd generation Intel Core processors at the same speed. That will place the Intel Core i5-3450 just under the Intel Core i5-2500K if you were not going to overclock it.

Thanks Chris. Any ideas why review sites have been so slow with the benches?

No one really cares about the 3450, same happened with the 2400. Everyone cares about the 3570K and 2500K.

Thanks for the useful info.
Should I consider getting an i5-3550 instead of the 3450? Is the difference between them substantial, or is the i5-3550 a simply faster clocked version of the 3450? Where I live here, the difference between the price of both of them is ~$30, I would gladly pay that if it makes a difference.
One thing more is that, considering the fact that both can OC to a max of 3.9GHz, and if we benchmarked a 3550 vs. a 3450 both @ 3.9GHz, which would you think will win?

The i5-3550 simply has a higher clockspeed (200MHz I think) compared to the i5-3450. In the US the price difference in only $10 so the i5-3550 is an easy decision.

If the price difference is $30 in US equivalent currency, then I would be inclined to get the i5-3450. If it was perhaps $30 Hong Kong currency, then the price difference in US currency (about $3.50) is quite small which makes the i5-3550 a better deal.

Nah 2500k is not gonna beat 3450 because in ivy bridge you can utilize intel applications like intel rapid start technology,extreme memory profile,intel gaming advantage etc compare to 2500k you can handle overclocking features bit much more than 3450 but 3450 has a 22nm processor which is must faster than 2500k 32nm processor for example a 2.4 32nm processor is equavalent to 2.2 22nm processor
