Hi everyone, unfortunately my mid 2011 iMac has just succumbed to video card failure. I've decided to switch to the Pro line so I could more easily fix the machine myself should anything go wrong with it. I've pretty much settled on an early 2008 Mac Pro 8 core with two Xeon's @ 2.8Ghz. The machine was upgraded to 10GB of RAM and has an HD 5870, as well as an SSD. It also comes in the original box. On top of all of this, it's priced excellently. However, before I buy I don't want another machine with a known issue like my iMac had, where its HD 6970M GPU was prone to failure. Also, I'm fine with the Mac Pro only going up to El Capitan as well as it being from 2008. The Xeon's inside of it are more powerful than my iMac was and that was perfect for me while it lasted. Just want to know if this machine will break after just a few months of ownership like the last one did, and if so, how much would it cost? Thanks.
