I have a Q9550 processor with 4GB and a Nv 9800GT video card.
My computer is set up as a multiboot environment (using linux's GRUB boot loader and its possibilities to hide and unhide Hard Drive partitions)
so that I have room for 3 versions of MS Windows, each installed on a partition visible to it as drive C:
Currently I have Windows 7 Bèta 64bits, and Windows XP pro 32bits installed.
Due to the memory allocation problem in 32bits versions, I think that the best I could do is to try PowerDirector in Windows7.
I have read some discussion where it is said that XP 64 bits is the way to go, but generally there is only a very limited amount on info on which OS is best suitable to install PD on.
I am planning to do AVCHD editing, so for bigger projects it would be nice to be able to use all RAM in my PC.
