Ok thanks guys!
I finally fiddled my resolution so it is enjoyable! Right now I have my URU:CC running on my main screen while I'm browsing web on my 2nd screen. (If you have space for 2 screens... go for it, you won't regret it and won't be able to have a single screen after, I'm telling you ).
So here's my set up:
windowed mode
hidding task bar
1600 x 1200
After the game starts, I recenter the window on my screen so it leaves me with 2 inches on each side. The image isn't stretch at all.
