Hi all. I have a 2007 aluminum iMac that my brother wants to buy from me. It is a 20", 2.4GHz Core 2 Duo with 2GB RAM, OS X 10.8, 320GB HD, and the 256MB ATI RADEON graphics card. He wants to connect our Wii to it and use the iMac as his monitor while simultaneously streaming the gameplay online to his friends. That way, the streamed gameplay is at its fullest quality to his viewers. I think he can do this using an Elgato video capture device, at least for the Wii as it uses RCA, but I'm not sure. Will this iMac handle it fine? We can upgrade it to 6GB RAM and an SSD if needed. It's the processor I'm a bit worried about. What do you think? Also, I would also like opinions on how to correctly do this game streaming setup if we have the wrong idea. Thanks in advance.
