should I upgrade to a 2020 IMac?
I've been using a 21" IMac since 2012, just lately its got slower and glitchy eg crashes occasionally, is slow to wake up and seems to use a lot of its 8GB memory (especially when I'm photo processsing). I've heard this could be a sign that its on its way out. So I'm wondering if I should upgrade now and what performance improvements I could expect?
My existing IMac has a 2.9Ghz intel core i5 chip and runs High Sierra 10.13.6.
Thank you.
