Maybe not a direct answer to everything but the specs on the main pixo site show a bit of range for min/recommended requirements.

I would say like most software if its not listed there then there is probably not “official support” for it.
Is there a specific thing that falls outside of the listed offical requirements?
If the item meets the same OS and other requirements it should work though
it may be more or less effective than another, like video cards. It may work
but this GPU is faster than that GPU. As for OpenGL vs DirectX I have not
come across any benchmarks. Runs smooth on my config.
Maybe we can make this a spec thread for you if it helps.
I run:
Intel Q9550
WinXp 64bit
4GB RAM
512MB Nvidia 9800
Wacon Inuous3
I dont run a RAID though my MB is capable but I imagine there would be no effect no matter the configuration (0/1/5/ or whatever, whether you are mirroring or striping and so on.)
Have a friend who has similar hardware and runs it on Vista-64bit.
Cannot answer to Windows7 as it is not out yet.
