Skyrim lags! drivers, monitor, or other?

Ok, so Skyrim worked great when I had it hooked up to a 44' 1080p tv.  I switched to a beautiful asus 24' IPS monitor...and it lags horribly.  I'm only getting 23 fps, use to get 60.  I have an asus r9 290x that I recently just updated to the catalyst beta drivers.  That's the only other variable I've changed.  I've gone to the settings and changed the aspect ratio of 1200p and 16:10.  any ideas?

Try using the non-beta version of the drivers as beta drivers can have alot of problems

yeah go back to 13.12 drivers, those beta drivers just suck.
