what processor configuration is better

Solution
Hello... https://cpubenchmark.net/cpu.php?cpu=Intel+Xeon+E5420+%40+2.50GHz&id=1233&cpuCount=2
http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i3-6100+%40+3.70GHz

The Future advantage will be with the i3 6100 setup.
1) an i3 6100 MB will have PCIe3 lane direct to the CPU for a PCIe3 GPU
2) AND upgradeable to i5 or i7.
3) and faster memory options.
4) 2x faster single thread performance. http://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+E5420+%40+2.50GHz&id=1233
