Question: Slow and flaky screen display on iMac late 2013 with NVIDIA GeForce GTX 780M 4096 MB

Hi. For a long while now I've had issues with the display on my iMac: 27" i7 3.5 GHz with 32Mb memory and NVIDIA GeForce GTX 780M 4096 MB card. Lots of spare space on Fusion Drive.

Main issues are:
Slow loading of fonts, particularly in InDesign using Suitcase 7

Flickery mouse in InDesign and Word for Mac particularly when several Adobe apps open at once

InDesign control palette freezes font choices until closed and re-opened

Grey bands across Acrobat Pro documents when Print Preview enabled
General increased slowness in loading apps.

Restart seems to provide temporary relief
Things actually got a bit better when I upgraded from El Capitan to Sierra but still not right.

I'm assuming it's a graphics card issue and am thinking I need to upgrade to a new machine but want to check if it's another issue before spending a small fortune on the latest machine. I've read stuff about using NVIDEA CUDA drivers but this seems to be for gamers not graphic designers!

I've not reinstalled from scratch as this is a big deal for me with all my settings nicely set up and fonts installed in Suitcase fonts, but I guess would eliminate any issues that had crept into the system.

Any thoughts gratefully received.

Thanks for your help. Wasn't sure which of the reports to run or if it matters but chose Computer running slow. let me know if I need to choose another option. I run Postbox as Apple Mail just doesn't have the features or deliver professional looking emails, but did wonder if this might be an issue as it is kind of bloatware for all it's features.

Here's the report (don't like the "below average" comment!:

Okay, first your computer is a mess due to what has been installed on it, primarily the antivirus applications. Mac OS was designed to be extremely secure and only needs to be kept up-to-date. It does not require ANY antivirus, cleaning or ANY other third party maintenance apps. Locate the developers uninstall instructions for the AV app you have installed.

After you have uninstalled all the AV apps (Sophos and ClamX) then restart the computer in Safe Mode to clear some caches and then restart and re-test. If the problem persists, create a fresh EtreCheck report and post it.

Good luck.
