ok but in order to solve a block is better submit less share with high difficulty or more share with low difficulty?

With a hashrate of 1 PH is best to use the proxy for submit share with high difficulties 500K and above or not use the proxy and have more connection for submit more share with a lower difficulty on average 70K.

Eligius pays nmc? I do not receive any nmc.
Thank you

Ciao stavo pensando di creare un rig con questi componenti base:

processorre: Intel Celeron G465 (1.9 Ghz) (TDP 35 w) oppure Intel Celeron G1620 (2.7 Ghz) tdp 55w
matherboard: ASRock H61 Pro BTC
ram: Corsair Ddr3 1333Mhz 4Gb
Scheda Video: EVGA GTX 750 Ti con 1.255 MHz Core, 2.048 MB di Memoria (5.400 MHz) e PCIe 3.0
oppure : ASUS PCI-E N NVIDIA GeForce GTX 750 Ti 2GB

volevo un parere sulla configurazione del rig in particolare sul processore da utilizzare, preferirei prendere quello che consuma meno Celeron G465 se non influisce sulle performance del mining.
