P55 vs x58 chipset SSD performance

[Pyrolistical]

Is there a performance difference? Do they both use ICH10R?

I am getting a 3x 60 GB Agility in raid 0 and was wondering if I could go with 1156 instead of 1366

The P55 chipset is pretty much a southbridge, like the ICH10R is for X58. Don't really need a northbridge because the cpu has the memory controller and the pcie lanes. So, if you're using intel raid on either chipset, you're going to have to go across the dmi link for communication back to the cpu and memory.
