Hi Benjamin,
For EVC L5 compatibility you want to be looking at one of the following Intel CPU models:
- Ivy Bridge: E3-1200-v2 Series
- Haswell
I'd recommend sanity checking this before rushing out and buying a CPU, though a cheaper option would be, as Jon mentions, to suppresss some fo the CPU compatibility checks though this obviously isn't desirable in a production environment and should only be applied in your home VMware study lab.
Hope this helps,
Simon
