What they didn't mention is that there is a hack that can be applied in Windows (possibly in Mac as well, though I haven't heard of such a thing) which tells Premiere that the video card is capable of using the Mercury Playback Engine. The poster above mentioned being weary of what video card you buy to make sure it works with Adobe's new rendering issue (this isn't necessary, but greatly increases general workflow speed, everything from previewing to rendering). PC has more options for hardware and video cards. Mac CS6 has apple pro res which is just a great intermediate format. However, each has a specific advantage over the other. I have noticed that CS6 is slightly more stable on PC than Mac, but hardly. I use CS6 on both a mac and PC (mac for laptop use and PC for desktop).
