I've seen a lot of people asking what they can do to upgrade their PC and to me at least there seems to be a lot of confusion as to what is affected by what component.
I've made this list of which piece of hardware most directly influences the speed of which part of the emulation. In theory at least if one of these options is causing you slow-downs, you should be able to pin-point which piece of hardware is responsible.
I'm sure that this list is in no way definitive. Things like bottlenecks may confuse things, but it might be a good starting point.
GPU dependent:
Internal Resolution (IR) / Full-screen resolution (if IR is set to auto)
Anti-aliasing
3D Vision
Disable lighting
Disable per-pixel depth
Cache display lists
Disable fog
Skip destination alpha pass
Widescreen hack
CPU dependant:
DSP (HLE or LLE)
CPU emulator engine (JIT or JITIL)
Texture Cache (Safe or Fast)
Both:
Embedded Frame Buffer (to Texture or RAM)
External Frame Buffer
Negligible Performance Hits:
Anisotropic Filtering
Force Texture Filtering
Fast Mipmaps
OpenCL
OpenMP
Progressive scan
Leave alone:
'other' hacks
