Anyone know if the official 11.10 will have the Rage performance driver included or will we have to keep on using the 11.10 preview 3's ?

That is a very good question!
I am waiting to see that one myself with all the freezing going on currently.

official driver 11.10 will be arrived in tomorrow (Halloween day). so if you want to install 11.10, just wait for one more day. it doesn't hurt you.
