But please... You wouldn't be using linux as you did today if every single driver where closed. Because that would make linux windows. Yup we might have a better kernel than windows, but all the properitary stuff we put on that kernel, would make it as unstable as windows.
The fast moving linux model just isn't ideal for proprietary blobs.
But lets stop ruining this thread. I just think amd's open source linux model of support is better than nvidia's.
If you want to play a more demanding game you currently NEED fglrx. If you want to use a newer distro with Xserver 1.6 you already lost with your purchase. If you want to play only games which are absolutely not demanding and you do not wan to use wine, a much cheaper card would be enough.
"It works for me" fallacy. Fact is that it doesn't work for many other titles. Most of the time you have to get creative and do hacks to WINE for a game to even install or run, and the ones that do run do so at reduced performance/quality. Yeah, my favorite games work fine, but many others on my library do not; and it's not a driver issue because the games don't even install properly to play.
WINE as a gaming solution is far from optimal. Some games work, and if yours happens to be one of them then fine. But for high end gaming and running the latest AAA Windows titles, just bite the bullet and set up a small Windows partition.
