Ok dude there are 2 ways to approach this. First off, why don't I just emulate a GTX Titan with my 570? Why do we even bother to buy new hardware? You can't emulate more efficient hardware on your less efficient stuff and get the same performance as the actual thing. Secondly, how could emulation help more than just writing a better mining program? With emulation, you add a middleman, which I'm sure you know can only make things worse. At least you were pretty sure it wouldn't work from the start.
What are asic's ? pure cuda cores / radeon cores?
What about a QEMU / KVM / Custom ASIC ? It seems possible!
