Hi all,

So since I have a new gaming desktop, I have decided to use my old one solely for bitcoin mining (24/7), but even using the bitcoin profitability calculators, I am still confused on if I should start it or not.

My system specifications:

i5-2500k
Corsair H60 AIO Cooler
Asus P8 Z68 V-LX
MSi GTX 560Ti Twin Frozr II 2Gb (Core clock at 942 MHz, shader clock at 1884 MHz, and RAM clock at 2161 MHz)
Seagate Barracuda 1Tb
CM GX 650W PSU
Kingston HyperX DDR3-1600 MHz (4x4Gb)

Difficulty: 707408283.0515
Hash rate: I don't know how to figure this out (<-- Need help)
Bitcoins per block: 25
Rig Cost: I got it for free, so $0
Power Consumption: <400 Watts
Current price of electricity: $0.7/KWh
Investment period: 1000 Days

Calculator I tried using: http://tpbitcalc.appspot.com/

Can someone please help me figure out these things?:
How many MHash/Second does my GPU mine at?
Will it be profitable? Including electricity costs.


Any input is appreciated,
