Windows 7 beta and chess programs, opinions please!

[Ponti]

I have an "old" notebook with 2 GB and 2 GHz processor (Turion) and I´m thinking to give Win7 beta a try.
Dir someone already installed it and tried some chess programs with it, like Chessbase or Chess Assistant / Rybka, Arena, Chess Partner, SCID, Shredder, CT-ART,... ? Do them run well on Windows 7?

I am using Scid, Arena, Chessbase Light and Chess Assistant 9.1. They seem to be working well.
