i have a Late 2011 MacBook Pro 15" base model, intel core i7 2.2ghz. I'm wondering which of the older mac pro (towers, 2012 or older) will match i7 2.2ghz performance (either about the same, almost the same, or even a little more) when using Handbrake. my MBP apple care runs out soon, and i don't wish to use it for heavy CPU loads anymore. I want what steve called a Truck - a tower machine that can handle these high CPU loads and remain durable and quiet. so i want to get an older mac pro because i don't have loads of money.. i've been looking at 2008 Mac Pro's on ebay as they go for affordable prices, but is that going to keep up with a 2011 macbook pro with an i7 when using handbrake specifically? (i don't need this mac pro for photoshop or anything else, this really is about handbrake mostly) can a 2006 mac pro do the job? i'd really like some advice here, especially anyone who can compare handbrake use on the older mac pros vs the i7's from 2011. some people say the 2011 i7's smoke the Mac Pro's from 2008 and even 2009, but some say this is only the case in certain tasks. all that matters to me is encoding video.
