On his CPU-bound workloads he recently upgraded from a Core 2 9550 to an Ivy Bridge 3770 (both chips non-overclocked) and got about a 3x performance improvement on the CPU side, plus the machine uses quite a bit less power (it is a dedicated 24/7 machine). He also has a 3570 setup that is about 2.5 times faster than the Core 2 was.
Ivy also has the benefit of PCIe 3.0 so you can probably stack in more GPUs effectively if you have the motherboard slots for them.

In fact, honestly the discussion about switching CPUs to save power is a little moot anyway because the CPU is probably not kept at 100% 24/7. it might be kept at 20-40% if that. if the OP could under-volt his CPU, disable HT, down-clock the cpu, etc, he could maximize his savings without spending a penny.

Oh, I just can't wait for my electric bill to arrive!
