I want to upgrade, but I don't want to waste my time if the test release is unstable and buggy. Can anyone with some experience in this reply to me please?

what has been added to FC3?

The only issues I have with it it's kernel/nvidia driver related. I need the 3D to work!

It's a strong/pretty distro...

NOTE: Something weird thing happened to me yesterday. When I switched my desktop picture, Gnome kinda went nutz on me... My bottom panel kept dissapearing. But it went away after clicking OK 10 times...

I installed FC3 T2 on a fresh partition when it was first released and have been updating it with the development branch using yum. No real issues so far but had to install some extra packages to get everything to work other than the usual fixes for xmms & dvd viewing. For example, if you install hpoj and xsane, libsane-hpoj is not installed as a dependency for some reason.

As far as the kernel goes, I compiled a vanilla 2.6.8.1 kernel and everything works pretty well except that sometimes firefox decides to close before I want it to. This usually happens when many tabs are opening simultaneously. Nvidia drivers installed fine and work well.
