Motherboard compatibility - AMD

I'm thinking of upgrading my Ubuntu Studio PC, and to avoid all the problems
I had with the current one (lock or slow mouse on a setup based on an MSI
7312 motherboard), can you recommend a 'working' setup (specially the
motherboard, due to all the known ACPI problems with the RT kernels)? I
intend to "upgrade" my current setup (MSI board) with an ASUS motherboard
with a Athlon II CPU. Some of the motherboards I've identified are:
ASUS M2N68-AM PLUS - NVIDIA nForce 630a + Geforce 7025 GPU
Asus M4A785D-M Pro - AMD 785G chipset
ASUS M4A785TD-M EVO - AMD 785G chipset
Any of you have any of these boards working with Ubuntu Studio (with RT
kernel)? I also had a previous PC with the AMD780G chipset and had similar
problems with the RT kernel, that was the reason to change to the one I have
now (with the MSI7312 motherboard, using the K9MM-V chipset), but still have
almost the same issues - freezing after boot, mouse getting very slow after
some seconds / minutes of use, etc. Or can you suggest any other known
working setup?
Thanks!
Fernando
