ASICS are hardware, as in hard to get and expensive, but around 300 times more efficient than your setup.
The only problem with ASICs is that they probably don't exist. But thats another story......
Yes, they exist. Dozens of forums users are already hashing with one of the AVALON ASICs.
If the OP wants to hash with something decent (67000 MHs), he has to buy an AVALON ASICs. But the price of batch #3 is +5000usd per unit, so the expected value is very likely to be negative.
