I have a 30"x40" drafting table which I lay flat and set everything ontop. It has my two 23" screens for my desktop, speakers, and room for my laptop, food, drink, books, etc. I can stand at the desk or sit on a bar stool. Does good in the morning when waking up or getting some serious work done.
My setup for mostly gaming. Some graphic design stuff, but mostly gaming and browsing the internet. Just a small Ikea desk with an Acer 4k 28" monitor. The computer has a 4790k, 16gb ram, and a GTX 980Ti, both the video card and cpu are watercooled, so the pc is pretty quiet even while gaming. Gets the job done
