Did you consider C5/C5d ? they typically get to 3.5Ghz and have smaller DRAM/vCPU ratio

C4 spot instances work for me at the moment. The price increase for C5 wasn't worth it as I was only seeing a 5-10% performance increase. I need to re-benchmark though.

I don't know about spot pricing, but on demand pricing for c5's is about 15% less than the c4's.

If you look at c5d's with ephemeral storage they are still a bit cheaper than c4's.
