I have a 2009 Mac Pro, and was wondering if it would be possible to put a PC 4870 video card in it and only use the 4870 in windows with bootcamp, and use the GT120 in OS X?

Mac Pros from 2009 (ie. 'Nehalem'-variants) can be configured with a HD4870 from the Apple Store. To my knowledge, these are ordinary 4870s with a different ROM that enables them to work with Mac OS X and Windows (otherwise one wouldn't be able to run Boot Camp with these cards). If you can get a copy of this ROM and flash your non-Apple HD4870 with it, it should offer the exact same functionality as HD4870s ordered from Apple.
I have no experience with flashing video cards, however, so you may want to confirm this with someone who does.
with a 120 booting the mac you might have more fun with an nvidia GTX card on the windows side - one set of drivers makes life a lot easier and both cards available if you want, for GPU stuff...
