My MacBook Pro from 2011 is still “good enough”.
I have a 2011 17” Macbook Pro and a 13” 2012 Macbook Pro. Both still work great. I replaced the HDD with 500GB SSD’s and they both are screamers. The 17” has 2 27” Thunderbolt displays connected and I use it as one of my home PC’s when I don’t want to power up the 2009 Mac Pro 12 Core beast (It draws a lot of watts).
I bought a 2011 MBP earlier this year. I figured that if I regretted going cheap, I could always flip it for pretty close to what I paid. I upped the RAM to 16GB and replaced the hard drive with an SSD. The only serious limitation is that it lacks USB3, and that doesn't bother me often.
Aside from gamers, desktops and laptops have gotten to the point where even Microsoft can't make them unusably slow in a few years. I'm running the latest Photoshop on a five year old machine, and it handles it like a champ.
