I have a very old desktop which I want to replace/upgrade. I really like lots of screen real estate (the old system has two monitors) and I want to have two 4K monitors on the new system. I am not a gamer and I do not do video editing but I do dabble in modelling (Fusion 360). What desktop specs do I need to drive two 4K monitors at 60 frames per second? I've been told that I need a gaming system but they are a bit pricy for my wallet. Thanks, Bob

What you have to consider is how much of your 3D rendering is reliant on the processor and how much by the graphics card. I do a lot of image processing, ( still images) and have no issue running two 4K monitors for use with Lightroom using a GTX 1650 4GB card, I also have a laptop (in my Specs) with an internal mobile 1650 Graphics card and I have ran 3 4K HDR screens, but I use a Rysen 5950 processor as Lightroom edits via mathematical formula manipulation, this should also be the case with 3D manipulation too - Check the specs suggested to run your most advanced software, in you case your 3D software and set your specification when shopping to that
