Profitable ? You never said how much you paying for electricity , that is one of the main factor

What is your kwh/$ price with all the taxes and fees ?
You can not mine Litecoin with GPU's anymore... YOu need asic hardware for that to generate any profit ...
Oops. Forgot to mention that. My electricity runs between $0.09 to $0.11 per /kWh.
I also want to reiterate that Im not building this rig solely for mining, but wouldnt mind using it for mining if I could recoupe the cost of my rig.
In other words...use mining to pay for the rig then use it for graphics design and video editing like I was intending on using it for.
What you choose to do after paying back your initial investment is, of course, up to you. The question is if you will recoup the cost of your rig in a reasonable period of time (or at all). The estimates for getting another rig (from scratch) at current exchange rates and hardware costs (for most of us, at least) are not encouraging, but it is largely a guessing game, regardless.
