I bought the base 2012 Mac Mini last week and I need to use parallels for Sony Vegas and capture software via Xbox/PS3. It keeps lagging constantly. I am looking to return the Mac Mini and upgrade to a different desktop option. I currently have a rMBP and it runs parallels with no lag. But I would like to run it on the big screen without thunderbolt displays. Would a the base iMac 27 be able to handle this with no lag? Or should I look for other options? P.S I understand I can put the rMBP on my display via hdmi, but I am looking to use the iMac with my other displays I already have.
