Mininum requirements for transcoding 1080p?

Greetings from Brazil, guys!
I'd like to know what's the minimum requirements for Serviio to transcode 1080p videos?
Well, I'm using Popcorn Time to download a 1080p torrent, and I'm trying to send that to my PlayStation 3.
It is impossible. The video doesn't run smoothly on the PS3.
I noticed that ffmpeg ran by Serviio on my computer can't transcode the video fast enough.
I'm using a mid-2010 macbook pro. It has a Intel Core 2 Duo 2.4 GHz CPU and 8 GB of RAM.
Do I need a more powerful machine or what? Remembering that Popcorn Time itself, with its torrent downloading, already consumes A LOT of CPU resources.
