Additionally, to prevent you from being misled, the Intel E3s have a limit of 32GB RAM and don't come in dual processor format, for 64GB RAM you would need an E5 Processor, for Dual Processors you'd need a E5-2*** - If the E5 is something like a E5-1620, that is only available in single processor format and not dual.

I hope this information helps shed some light on the sort of server specifications you should be looking for. @krnel Happy upgrading :)
