Best driver for AMD Radeon HD 4850x2?
I installed Linux Mint 16 on my older computer but the official AMD legacy drivers won't work. Is there some other open source driver I could use? I'm pretty new to Linux so I don't really understand much.

Development of the legacy fglrx driver has been stalled, almost all supported distros are no longer compatible with it, including Mint 16.

There's only the free radeon driver left, which comes preinstalled with pretty much every distro out there. It is being used automatically, you don't need to do anything.

Yes, but you REALLY need kernel 3.11 or 3.12 in order to benefit from recent performance advancements. These are not yet default in most 6-month/etc. cycle distributions. It's fairly easy to do though. Search for how to install the kernel, and also how to enabled "dpm". You'll probably want the Xorg-edgers PPA for recent drivers as well.

Unfortunately you got in at a bad time: proprietary drivers aren't really great for your card. The Open Source drivers are -almost- there, but the software hasn't made its way out into most distros yet.

Mint 16 is still a RC and based on Ubuntu 13.10 - i.e. modern drivers, modern Mesa and Kernel 3.11.

Ah, I did not know that. In that case, it should just be a matter of adding the "radeon.dpm=1" string to the boot settings.
