What i have is the phenom II 920 not sure how much different that is
from yours, but I found the 64 bit OS was a bit much for it ( 4 G of
PC1066) and it can't handle the load. Constantly crashing or
freezing. Video display was very shaky and boot up time was
extremely slow while I had 8.10 on there. So then I switched to
9.04 RC Boot up time was better, but videos were still shakey.
Definitely not capable of multitasking which is what it was supposed
to do best !!!! Currently have a 32 bit Kubuntu 9.04 installed-
not happy with that either altho it did seem to clear up the
resource overload and videos are steady.
Im going back to the Ultimate Edition 2.1 (because thats what Im used
to) but this time with 32 bit - hopefully that will give me a
useable machine. Kubuntu is missing two vital features for me One
is Wine - not even available in the add/remove programs and the other
is DC++ without which I simply cannot function also not available
for download. I started with Gnome and now going back- Kubuntu is
very pretty but not for me. Someday when I can afford more RAM
I might give the 64 bit another go.
Right now I just need to be able to use it.
