If Emulation was completley optomised.

[Infern0]

Say if we were 5 years down the line, and we had Dolphin version 3.0, and it was completley optomised and perfected.

what sort of specs do you think it would need to run?

I only ask because right now you seem to need a quad core and a high end GPU to get anywhere, yet the Gamecube itself only had a pathetic 400mhz cpu, and not a very good gfx processer either.

with most emulators after the 1.0 version, the hardware reqs seem to come down with every release.

Oh i also meant to say, I can play games like Oblivion and Fallout 3 and GTA 4 etc on my pc (which are PS3 games) and yet i cant get Wind Waker going at a reasonable pace

Impossible to say. All I can say is it will likely be much more demanding that it is now. Emulation requires a lot of stupidely inefficient things to be implemented for accuracy that no sane person would do with native software.

Games ported natively to the PC are vastly different than true emulation. In those games your computer's processing the code directly; in an emulator, you're actually processing an entirely different CPU with its own unique instruction sets. You simply cannot take a console game and slap its image on a computer expecting it to run correctly. As NaturalViolence said, emulation is nasty work. In emulators, accuracy > performance. Accuracy is also extraordinarily demanding. I'm sure that we'll be seeing more optimizations here and there, but don't expect the hardware requirements to go down too much.
