Hey everyone, I'm going to buy a Mac Pro, unfortunately it will be a second hand one as I don't have deep pockets. I'm looking on ebay and there are some good deals there but I'm not sure what to get. I'm only using it for streaming tv and a bit of music production. Looking on eBay there are some with single CPUs and some with dual CPUs. Would there be any advantage to getting a older two dual core Xeon CPU machine or get a new quad core machine ?
