I just went the other way…from Win 7 to Mac running Mavericks. C7 ran great for me on Win 7, no complaints. I have no idea what it would be like going to Windows from OS, but I imagine it wouldn’t be that difficult…but completely different from Mac world. The only issue I can think of is drivers and hardware, because there are so many components available for PC (unlike Mac, where components are are compatible), and you’ll be dealing with ASIO. If you get the right combination, you’ll have a solid system. I agree Mac is stupid expensive, but I did it for portability reasons, etc. And really, I have yet to experience any performance differences; I always hear that there are, but not sure what they are yet. I just read that a 12-core Mac Pro with 65GB Ram will set you back $9k!
