The only reasons I see given for choosing a 2500k over a 3570k is that the 2500k can be OC'd higher, or if you are an avid gamer. OCing a 2500k to beat the performance of a 3570k also means you get less output overall when compared to power cost.

I'm not sure that 2500k is faster. I own one of each, and my 3570k is slightly faster. But different memory and OS.

The speed at the higher FFT levels (where first time tests are now) depends on the memory.

Maybe 3570k is recommended because it feels better to have a newer model, or because it is specified to run a few watts cooler.

If I was going for a 5xx series gpu you could go for either. For a 6xx series I would recommend the ivy bridge because of PCIe 3.0.
