I would use the E5-2670 V1 as close and so your number looks right.Ok, just stopped the eth mining and I'm at 750-860H/s. On the mining performance thread it shows 969H/s for the E5-2680 V3, but I have the V1 so I guess this looks alright?
Because I'm using minergate, but does't look so stable, the hashrate varies frequentlyNo, they each use different pool - server - for connection. You have to choose one and register an account there (you can have an account at each one too). Each pool has it's attributes, like amount of pool fee, payment options, etc...
In May I've put two same servers on these pools - one on dwarf and one on monero.crypto-pool.fr.Total Fee: 2% (Reverse 3% pool dev, 7% to core devs) for the above pool.
Dwarfpool is 1.5% and 0.01 XMR for autopayouts.
How is the .fr pool paying more than dwarfpool.com?
