You might try turning the twinview of, it takes up heaps of resources
on my machine, then again, your machine has 300% more RAM and
clockspeed, so it should be able to handle it fine....

Try using freebsd AGP, the nvidia should work better but you might
want to try it anyway...

Which window manager do you use, I noted that KDE can be really,
really slow even on newer machines (Krap Desktop Enviorment)

Is this problem ONLY with opera? or with other applications to? if you
have another QT application you might want try how that runs.
Also check you QT version, maybe it's ancient?

Did you try using both the static/shared QT versions? If not, it might
make a diffrence.


Don't post your dmesg again please, it makes me drool which makes my
keyboard dirty..
