Wow I definitely forgot to reply here
. Thanks guys
The catch is, I've tried it but still don't really see the need. I feel like this 23" screen is way more than enough and on the rare occasions where it isn't it's only then that I need to turn on the second screen. As far as monitoring temps etc, I don't care enough to turn on the screen, and if it's really an issue (it rarely is) I can just alt-tab.
When I moved from 4GB to 12, a friend suggested I just not close programs, and I've found that that's really great since I tend to be able to switch between things now, but with this other screen, I still can't seem to find a regular use for it which is incredibly disappointing. .
