hey guys, I haven't posted in a while.. Im a long time music producer, and as of late 2012 have moved into the media world. I had purchased a 5d mark 2 with a few prime lens and I have been doing photography and event filming. I have a 2009 13 inch mac book pro that i have had upgraded to 8 gigs of ram and a 750 gig hard drive.. Its my first year and I have been able to do some great work with my mac book pro but it's choking.. Doing video editing it gets sluggish and editing pics on lightroom and aperture doesn't make it any easier.. I decided to pick a refurb mac pro. I got it for less than 500 bucks. The only problem tho is that I can't get the latest os on this. Is it still a good machine for what i am using for?
