The best bang for the buck card out now is the HD4850. The HD4770 is out of stock nearly everywhere and I even heard rumors of it being discontinued. The HD4830 is the best card you can get in the sub $100 range right now, but to be honest, I would stretch my dollar a bit more for the HD4850. There is no reason to go for the HD3870 since even the HD4830 is faster and both series of cards have similar driver support in Linux. Memory wise, 512MB is good for most things, but I would consider 1GB if running games at a res. bigger than 1680x1050.
As for driver support, I honestly wouldn't expect anything from the open source front until at least year's end. The HD4K series has good 2D and video playback support with both open drivers, but 3D is still a ways off. If you want the most out of your new card you're going to have to stick with fglrx for the time being.
