Questions regarding multiple displays/Multiple Resolutions

I have a 6870 and have a few questions.

My current setup is this:

2x 32'' 720 TVs. XFX 6870

I want to upgrade tot this:

1x 40'' 1080 3D tv + 1 32'' 720 TV


I hope that isn't confusing. I want to use one 40'' 1080p tv (with 3d) and another 32'' 720p (non 3d) tv as a 2nd monitor. Will i have any problems using two different resolutions on the TVs? Also how is 3D for gaming/movies on a screen of this size?

Yes i realize the TV's will not be even and therefor will not matchup, i'm fine with that. I just want to be able to use my 2nd TV as a 2nd monitor so i can drag applications over there when i need to see two things at once.

Thanks for the help.
