Its finally time to retire the Mac Pro 1,1. I am about to pull the trigger on a new 27" iMac and was considering upgrading the video card to the M395x but sticking with the i5 processor. My main concern is longevity of the machine. Through tinkering and upgrading I have been able to keep my Mac Pro useable for nearly 10 years. I don't expect to get anywhere the the life out the iMac as I can't really upgrade it like the older Mac Pro, a couple years back I upgraded the video card in the Mac Pro and it really gave the machine a new lease on life for quite awhile. Would the upgraded video card keep the iMac feeling current longer than upgrading the processor, what might be the best upgrade to consider? I use the machine daily but I do not do any video work or anything else really taxing other than once and awhile and play a few middle of the road games for entertainment.
