Is it fine to have 4870 and 2 GT 120s in Mac Pro?

I have a 2009 Mac Pro and currently have a 4870 and a GT 120 in the Mac pro which I have 2 24in ACD displays hooked up to.

I'm going to be purchasing the 27 iMac and using it as a Monitor until they refresh the 30in ACD although in order to do so I will need to add another GT 120 into the Mac pro in order to have the third Mini Displayport.

Is it ok to have 2 GT 120s with the 4870?

You shouldn't have any issues.

The Mac Pros have quite a hefty power supply so running those three cards won't be an issue. Now if you were to say try and rig up 4 Radeon 4890s then it might start looking at you funny.
