since three days i'm using my nvidia 295 gtx for mining.
overall it calculates between 60 and 120 MH/sec. (i don't know why it drops down sometimes...)
but 100MH/sec is much to low for me...
so i'm thinking to buy a pc only for mining! (in august)
cpu: intel core i3-2100 95€ 65W
mb: ASUS P8P67 WS Revolution Rev 3.0 207€
graca: 4*Sapphire Radeon HD 5870 155€ each 188W each
ram: g.skill 8gb ddr3-1333 51€
power: Xilence Modular Series 1200W 150€
the system should calculate 1600MH/sec.
it sould "produce" 85$ per day. ~60€ (i estimate with 30$ per BTC)
so in one month: $2,586.87 ~ 1800 €
if i calculate the fees and so on i estimate about 1200€ per month.
my adwantage is, that i don't have to pay for the needed powerusage
what do you think about this systhem?
is my calculation right?
does somebody know why the btc/$ rate decrease so much yesterday?
pp: sorry for my bad english
