Having been a loyal 25+ year Mac addict I have finally lost faith. I've wasted the better part of this year for a decent update. It's not so much the cost factor than it is buying a machine that it near the end of its life cycle.
For professional use I could get by with just Lightroom, Photoshop, After Effects, and Premier. For video I am a FCP user but am happy to switch to Premier if it means I finally get a new computer and not one that's 400+ days old (current Macs).
I am not a gamer. I don't see much need for a blazing graphics card (my needs are more CPU based).
I would like to spend ~$3000 for computer and 27" monitor. I know NOTHING of PCs.
Does anyone have any recommendations?
Yes - buy a Mac Pro. Buy a superseded one if you like.
I did ... and I built a PC games machine for Christmas. It wasn't cheap, and hasn't been close to bulletproof. Its noisy too, despite water cooling.
For instance, a Quad Core Xeon Mac Pro "refurb" (most likely its never been used just superseded), costs in the USA, $1,900. You can upgrade it to 6 core, for under $500. Or just leave it until you need to upgrade the performance by 70%.
The twin CPU machine costs $2,700. It cost much more to upgrade (having two CPUs), and its Xeon processors being the 5 series need to be used, due to the twin operation. But ... they'll get cheaper next year too ... but if you need bang for buck now, go the single, and upgrade to 6 core if you need more speed.
By the way, the power supply in all the Pros is 1200 watts, and the best quality. The case is excellent quality. The same quality as the $4,500 machines. Xeon is stable - its a workstation.
Add some RAM - that will cost more than a PC, because its error correcting RAM. But .. that's why its reliable.
Drives etc are just PC drives. They take two minutes to install. Pull the plugs out, de-stat place, remove the door, slide out the drive bay, put in the drive, slide it back, close the latches, put the door back, close door catch, plug in, turn on, off you go.
Time machine - pop in a 3GB green drive for $150, turn on time machine, you have great back-up, and you can go back to earlier work.
Buy a NEC 24" spectra view with calibration software monitor for $1,200. Then you get reliable colour.
$1900 + extra drive = 2050. Plus screen $3,200. Plus RAM $200 = $3,400. Plus an SSD boot drive for $200. $3,600.
And it is easy to upgrade, has a genuine second hand price (it will not disappear in value), and it will be bulletproof.
You'll then get workstation reliability, and quite a lot of performance. You will save when adding disks etc. A USB 3 card is cheap for them. Plug in an SSD - it takes a couple of minutes to do so.
They start at under $2k now.
The tough thing then is the screen. Spend some money on that, say a NEC PA 24" and the Versa hardware calibration system, and you'll be eating next years iMacs for dust.
