Thanks for your input! Is there a PC type you recommend? I only use Chief Architect and some AutoCAD. I will have to use Revvit and more Sketchup in the future and add a bit of gaming in there (nothing extreme). I don't know how much additional RAM, video card etc my pc may be able to handle, but if it would cost less than 1.5k USD, I would rather do that than buy a whole new PC with new monitors and accessories, etc that may add up to 3kish.
