So now you have your 2 boxes producing 250+MHs scrypt using 2500W of power. You have a 5KW renewable energy source, wow VTC is going places. I stick my 250MHs on a pool that converts scrypt to VTC. This is now the equivalent of 125MHs at 2500W. Using the most efficient hash/power GPU, ie 750Ti, let's do a calculation:

1.8MHs at 450W. But wait it's scrypt-n so 900Khs at 225W. 2500W will give you about 10MHs on pure VTC. You'd be getting 12 times more return from mining scrypt and exchanging to VTC from a power perspective. These numbers don't seem right so please chime in and tell me where this went wrong.
