What can I mine with this :
2 processors Intel Xeon E5420 2.50 Ghz
16GB RAM
Windows 7 64 bits
I have a dell precision with a dual Xeon 5600. When I tried to mine ZEC with nhqminer, I was barely doing 12S/s for 150Watts. This was a week after Zcash launch, maybe updated versions of the CPU miner can do better now but I doubt it (can someone confirm?). Other than that, I wouldn't waste my time with a power hungry Xeon...unless you have free electricity.
