True. Mine is 4 years old, and isn’t struggling one bit.My 5K iMac is over four years old. I ordered it with the best graphics card and processor at the time, and I maxed out memory and the SSD. Nothing I’ve tried slows it down, including editing 4K video in FCP X. The only thing I wait for is when Compressor renders a batch of video.
I’m really bad about having G.A.S. (Gear Acquisition System). And I keep looking at the new iMacs and specs then I feel silly because... well... mine is just fine. Absolutely NO way I can justify the expense.
