Thank you David for the quick reply.
I was swaying towards 27 inch, my last pc had a 24 inch screen so going down in size would be a bit silly.
My follow up question is what size SSD should I choose? I can't afford to go too high. Surely all you need is enough space for one project at a time, that gets put on the SSD, and all other projects can be stored on a slow external HDD? How much space is needed for 1 project plus everything else that logic needs for that project?
