anybody use dual monitors?

Indeed, for several years now... when at work (retired now) and also at home (I play a few online games :) )

Yes. One monitor is for chumps. ;)

Chump here with one monitor. :)

I don't even have room for one desktop. I took the desk out of my room for extra space (after my last desktop got a virus and I bought a laptop and decided never to use another desktop again) and use a laptop now.

The only time I use two monitors is when I'm building something and I'm looking at google pics architecture or interior design for inspiration.

Always. For work (at work) and for play (at home).
1 is the main one, for the game I'm playing or thing I'm writing or page I'm actively browsing, one is the off-monitor for, well this forum right now, or youtube in background etc.

tempted to buy one so that I can play sims whilst having things open in different monitor screen

I use 3 monitors on my desktop.

Do it, its very good, my sim is raking right now so I'm here on forums and on youtube :)

Just make sure they are somewhat similar in quality (aka if your current one is old and crummy the new one will be very different feeling).
also practically speaking, make sure both have same kind of lift/raising features (aka u cant raise at all or can lift monitor higher on its own stand) - i have to stack my 2nd monitor at work on boxes to make it match in height

Of course. Once you're used to it, it feels so bizarre to just have one.
