msi 670 PE sli vs Asus 780 OC is there a significant increase in performance

[bjkill]

Hi I currently am using 670 SLI from MSI and it the PE edition. Am thinking of upgrading to water cooling GPU's so am thinking of getting one Asus 780 OC and an Asus Poseidon 780. I am doing that because the Poseidon has GPU stress light and also factory water cooling options. I will then use a NZXT Greken 10 to water cool my 780 OC version with my H110 CPU cooler.

Question:

Is it worth it to change from 670 SLI to 780 SLI? I only play BF4. So am only interested in performance difference in that game. Please advice thanks.
