getting a mac isn't going to change anything. you have an impressive system, but all you need is a little patience. there's really very little we can say to you until we see what you were working on. details. did it have volumetrics, soft shadows, a hundred lights, detailed textures? how big is your scene file, both in terms of pixels and mb? are you trying to render it at maximum settings? what are your render settings? no render should take more than a maximum of 2 days unless it's something truly epic and you're rendering everything in one go. try doing a bit of postwork instead of volumetrics, render things in two or three layers instead of one, etc. drac
