If that's to me, sorry, didn't mean to jump on ya. It's all in good humor... Potato chips and salsa, hehehe.
The plain and simple fact is a processor like that and a video card with only 16MB video RAM is hardly ideal for emulation. But if it really does seem to work well enough, you could try the "Azimer's HLE Audio v0.56 WIP 2" audio plugin. It's supposed to be particularly good at reducing crackle in the sound. You might also try using the Rice video plugin, specifically for the frame skip. It's worked wonders on my laptop, and may help to reduce some of your video card-based lag, because with a rig like that it's probably your biggest problem.
