Would you upgrade the CPUs in this server?

I currently have an R730XD with dual E5-2630v4s (85W). CPUs for this socket are dirt cheap. I have dual 1100W PSUs. I'm not concerned with electricity cost, but I don't want a black hole of power either. I am looking at E5-2698 (135W) and E5-2695v4 (120W). The system has 384GB of RAM, an array of twelve 2TB SAS SSDs, and four 10Gb SFP+ ports. I just feel like the CPU is worth upgrading considering the other specs.
