I'm a doctor and a tinkerer, and I
hate waiting for my computer. I basically use it to surf macrumors forums. For that, I was happy with my mac mini. A few years ago, I was tasked with converting about 50 hours or so of home Hi8 and Digital8 videos to digital format. The mac mini (without a 980Ti attached) simply couldn't handle the conversions. Thus began the quest to find a computer that would do it quickly enough. Since I have had bad luck with iMacs (they all get glitchy on me after 3 years), I went the cMP route. It satisfied the tinkerer in me as well.
Also used for:
Civ 5 now and then
Photos (RAM is nice
Relatively basic music production with Logic and Sibelius
FCPX (for old movie conversion and ongoing home video messing' around)
Quicken
Numbers
Forklift (great program)
Rome: Total War occasionally
Setup:
MP 5,1, 48 GB RAM, XP941 500 GB drive, 4 spinning drives in RAID 1, MVC 7970 video card, 12-core 3.46 GHz, BluRay burner in the extra optical drive. ACD 30", which I got used a few years ago.
I have had it for going on 5 years now, and it's still rocket fast. I don't want to turn this into another cMP vs nMP thread, but I'm going to keep my cMP going as long as possible.
Hands down, the most awesome upgrade was the XP941 installation. It's unbelievable how much faster the computer functioned after that. I guess there are faster disks now, but mine has functioned flawlessly since installing the 941.
