:lol: yea, I know what you feel. sometimes it's frustrating. but the more patient you keep trying, the more you will learn how to improve the setup to get the sim you want as fast as possible.
of course, you need a good machine. As jordan said, 8 cores with a lot of ram are doing well. When you're working with a lot of particles, or detailed emission objects, then all these informations have to get located in the grid which takes time and is single threaded. this for I think you need a very strong core and fast datatransfer. and of course when it comes to the simulation calculation, the more cores the better
but you can shorten the simulation time by setting fume up correctly. proxy objects will do the first step. don't simply crank up the grid resolution for no needs. quality and iterations are most of the time set to high. turbulence is a killer. try to avoid. long vectors increase sim time too. don't use to big grids when not needed. for example where the camera is not looking at. keep in mind that the spacing value is the length of one voxel. I do always orientate my setup to this value so I know what settings to use, velocities and size and stuff. hope this helps a little.
