Does anyone know the max resolution output the 2012 Retina MBP supports? Wanting to buy a 1440p monitor.
2560x1440 shouldn't be a problem. Depending on what you wish to do on that monitor, and at what resolution, your computer might need to work noticeably harder, though.

However, if you run it in clamshell mode (screen closed) when connected to the external display, it will actually need to process fewer pixels than it has on its own screen, so in that case you might even see an improvement in performance.

It should be fine, though, if you have the 15" rMBP, then of course you'll have the dGPU. The 13" rMBP's iGPU may lilit under trying to drive both displays, so the advise of using it in clamshell mode is sound

Yeah I use a clamshell HedgeDock atm with 2 1080p monitors.
