Mostlikely not. Two xeons on a dual cpu motherboard with large amounts of ram will do, though.
Edit: Sorry, disregard above.
Yes, a high end xeon will do better than the i7 5960x in productivity, but not in gaming. For gaming solely, anything above an i5 4690k won't yield you any noticeable performance increase, though. http://wccftech.com/intel-haswell-ep-xeon-e5-2699-v3-processors-benchmarked-18-cores-36-threads-45-mb-llc-145w-tdp-hpc/
However, if that's worth the price tag, that is another question.
