I still think you should look at the i7 5820K, or the soon to be released Broadwell-E. The LGA 2011-v3 socket with DDR4 memory is still current and relevant, and six cores is better than four for VM.
The extra hyperthreading for an i7 would push me away from an i5. Without more details on exactly what you want to run and how many of them and what you expect to see and experience, we need to be conservative in our recommendations. An i5 might be enough for you, it would not be enough for me.
