Looking to upgrade the CPU on my 2 year old custom built system.
Currently -- aBit KN9 (not SLI, Ultra or S) AM2 motherboard, 2.0GHz
Athlon64 (single core), 4GB RAM, Fedora 9 (64-bit).

Was looking at just getting an Athlon64 X2, but came across an article
(several, really) saying that the Phenom X4 (AM2+ model, not the AM3 II
one) quad-core will work. Other opinions say it won't. AMD says the
sockets and CPU are backward compatible, but aBit doesn't list my model
motherboard as compatible with the X4.

Anyone have a system such as I'm considering up and running who knows for
sure before I take the plunge?

FWIW, I'll be upgrading to Fedora 12 a few weeks after it's released--
currently set for Oct or Nov--before any hardware changes are made. 12
is suppose to be a majorly "tweaked" version optimized for performance
and fast booting without too much "new" stuff compared to 10 and 11. So,
if there is notable improvement in performance, I may forgo changing the
CPU or just get an X2 which I know is 100% compatible.

Thanks.
