Someone asked about A series AMD machines a while ago.
I kept quiet because I
was in the process of getting one. Here is the spec:
MBO ASUS® F2A55-M LE
CPU AMD A8-5600K Quad Core APU (3.6GHz) & Radeon™ HD 7560D Graphics
MEM 4GB SAMSUNG DUAL-DDR3 1333MHz
SDA 120GB INTEL® 330 SERIES SSD, SATA 6 Gb/s '/' & /home'
SDB 180GB INTEL® 330 SERIES SSD, SATA 6 Gb/s '/audio' &
'/source'
I've now spent a few days getting it exactly as I want it. I made very few BIOS
changes. I disabled serial and parallel ports (the machine doesn't have them
anyway) and set the CPU to 'performance'. Initially I disabled the on-board
sound as I'm using my trusty 2496. But I got occasional boot oddities so
re-enabled it.
I installed a minimal debian-squeeze without any problems at all, then just
added the software I wanted. This was a bit harder than I expected as my notes
from last time were not complete, and going from Linux 2.6 to 3.1 meant there
were subtle differences, especially with stuff I had to compile.
The machine is very, very responsive and almost completely silent. The PSU has
a slow running 120mm fan and the cooler on the CPU looks like something from a
space lab!
With the stock 3.1 kernel I'm running at a latency of 5.8mS with no x-runs even
when going full steam on Rosegarden (with audio tracks) and Yoshimi. Sequencer
+ synth playing of complex material that used to peak at around 70% total
processor, now peaks at around 20%!
I did try the 3.2 kernel, both stock and RT but both of these actually
performed far worse, and I had to run with a latency of 23.2mS to get clear of
x-runs.
My old computer has been re-purposed as a (rather fast) office machine, so that
involved a lot of file swapping and checking that nothing was missed.
Now, I suppose I'd better get on and compose some music :)
Really cool, AMD does wonders but I must say that ATI Radeon sucks here...
It works, but everytime I do an upgrade I start to sweat, quite often
the card "dies" and I have to login from another machine with ssh,
kill X, unload and reload the kernel module.
Wish you good luck :-)

PS: for the sake of knowledge, debian wheezy here
