I noticed you were referring to a lot of fud and hearsay there.
I also didn't read anywhere that you were having the so-called problems yourself.
ATI literally has the best drivers in the industry right now, so I doubt that you will have any issues with that card, although it probably wasn't the best card to buy considering that ATI is making much faster mid-range cards available now, but that's your decision.
If you have a via motherboard, it is pretty much a requirement to install the latest via drivers.

Via had some pretty crappy older drivers (and boards) that can cause problems.
Use the latest drivers for stability and speed.
Nvidia has some pretty bad drivers too, especially with the nf2 and nf3.
Here is an updated driver for nvidia, which is fairly necessary for stability and speed on older boards.
It's sad that nvidia did not officially release these updates themselves.
nForce 11.10 Unified Remix (x32/x64)
If you are playing any recent games or just want maximum performance with your card, a hotfix driver was recently released here:
AMD Customer Care
You can also use Ati Tray Tools instead of installing the CCC, whatever you prefer.

I wouldn't use any "optimized" drivers if I was you either, most of the reliable driver sites quit modding ATI drivers, and all that's left is outdated stuff.
You're far better off to use stock.
BTW, I find it really funny that there hasn't been any recent ATI releases from the mod scene, especially with the fiasco nvidia put them through.
You'd have thought sites would have dropped nvidia altogether, but no...
