Hi Marek,
Thanks for your reply.
After some further research it looks like my choice for an AM3 board is
either:
older 760G chipset with legacy BIOS but no IOMMU
OR
newer 970 chipset with IOMMU but also a UEFI BIOS
I would be really interested in your views regarding this choice. Which
option would you go for?
(I will need to use bluetooth with this system, in case that sways you
towards a board with IOMMU.)
Regards,
Stephen
