What makes you think a Mac built with the exact same Intel CPU, the exact same DDR4 memory, the exact same GPU, and the exact same SSD will last any longer than a PC? If your PC is getting slow and unusable after just three years it can only mean one of two things:
a) hardware failure
b) user failure by trying to "optimize" and "tune" Windows into oblivion
Hardware can fail on a Mac, too, and if you managed to bring Windows to a screeching halt chances are you'll do the same with macOS trying to "optimize" and "tune" it. Neither Windows nor macOS require any sort of third party optimization. Quite the contrary: the more you optimize and tune, the more you break.
Long story short: a 3 year old PC is not old yet. Heck, until recently Apple used to sell iMacs with two year old hardware, Mac Minis with five year old hardware, and to this day they are selling Mac Pros with hardware released more than six years ago.
I just put a small SSD into a 2008 iMac, installed 6G of ram (maximum) and it boots fast and running ElCap. It's running fine.
I just purchased my first Mac computer. Always was a PC guy, but I wanted to try this for my photography. I bought the top model with 512gb SSD. I know it’s all relative to what programs you want to run and new programs coming out. I plan on using photoshop and Lightroom that’s about it. That’s all my pc really has but it is getting slower. Had it about 3 years. For the price I’m hoping I can go quite a bit longer on the Mac, so that leads me too my question of how long has yours lasted you and have you noticed a significant slow down over the years with new programs and updates coming out for software?
Older iMacs tend to last awhile as long as Apple didn't use cheap drives or GPUs in them and then deny you a repair under the extended repair program because your serial number was outside of the range that they deemed impacted. Newer Macs are pieces of crap designed to fail after three years.
Did you do all this work yourself? If so, very impressive! I have a late 2013 maxed out to 3TB when I purchased it and never imagined it could be configured for 9TB.I have a Late 2012 27” iMac that I bought when it came out. I maxed out the CPU and GPU options available at the time from Apple. I then upgraded the RAM to 32GB of RAM. Later I changed the internal storage configuration twice.
The first time from it’s original 1TB Fusion Drive configuration to a 1TB Crucial SSD. I also left in place the 128GB blade SSD. The second time was recently, where I change the storage configuration to a 1TB OWC blade SSD, that took the place of the 128GB factory SSD, and an 8TB WD Red Drive, for a total of 9TB of storage. At the same time I also replaced the existing internal AirPort (WiFi)/Bluetooth card to one from a newer iMac to get ac wireless.
My iMac has never been faster, to include Lightroom and Photoshop, also my two main apps. It's by far the best and most reliable computer I have ever owned.

You’ve read this thread, right? - https://forums.macrumors.com/threads/2011-imac-graphics-card-upgrade.1596614/My Mid-2011 iMac lasted 3 years until it had the infamous graphics card issue. Apple did repair the issue, but now, 4 years after the repair, the same issue is back and Apple refuses to repair it because the machine is "vintage". So it is now a giant paperweight on my desk. Otherwise I've had no noticeable performance degradation and I'd still be happily using it if it worked.
[doublepost=1560273940][/doublepost]Mine is a late 2009 and still running great, it slowed down a few years ago but I put another 4 gig of ram in and it was just as good as new. If I upgraded to a ssd it would be better yet but I haven't seen a need. I run Excel;Word,mail,Safari, and Parallels w/win 10 and no problems.I get a new Mac at work every four years so I'm not sure. This is my first personal iMac. But I can answer for my friend, who upgraded from a 2009 iMac, so about 10 years. I doubt I will ever go that long for daily use, but I plan on keeping this 2019 iMac in the family. I think it will be a great family computer for my kids someday. I do plan on teaching them how to use and appreciate Macs. I gave my daughter her first lesson the other day on how to use a mouse-based UI to set typography and she is 5 and she picked it up fairly quickly. They currently use iPads for about 30-45 minutes per day. The iPad is pretty locked dow I'm hesitant to get them Macs until they are in high school if Macs are even a thing by then (God forbid) because I don't think I can lock them down as tight. The internet is really freaking scary for kids nowadays. But I would let them use the iMac in a family space for doing schoolwork such as research papers that require lots of multitasking with windows side by side. Maybe by then the iPad will be better suited for tasks you can do on a Mac but who knows. I think a big display is still superior.

After seeing/reading about all the machines with added Ram and upgraded hard drives to SSD's etc. Leads the question...How long should one expect the useable life of an "off the shelf" 21.5 iMac be? Without doing any upgrades? using the stock 8g ram and 1TB fusion drive. What performance over time is effected?
