The 7850 is a great choice, (I use a 7950) but to answer your question. No, you do not need to reinstall the drivers, but go on the AMD website and download the newest drivers for the 7000 series (12.6). I do not recommend using the install disk. Also, if you want to OC I would use MSI Afterburner.
Be sure you uninstall the old Nvidia drivers also!
I'd say buy this http://www.amazon.com/Sapphire-Radeon-PCI-Express-Graphics-11200-00-20G/dp/B007JCNOZK/ref=sr_1_1?ie=UTF8&qid=1341189892&sr=8-1&keywords=7850
Sapphire is a great brand and I had the 6950 with this cooler and it works VERY well and is much better then ref. cooling.
