My system is a core i7 920 with 12 gig of RAM an Asus 6PT mB though I would also recommend gigabyte. It has run everything I have thrown at it since I made it.
For the first time since buying Cubase 3.7 around 14 years ago everything actually works.
I feel very happy with everything, including Win 7 which has never crashed on me at all. I ran Win RC for some months and this was also stable.

As for sample libraries 'bringing system to its knees', well with a little help from Jbridge My system runs EW platinum, some VSL, Kontakt, Halion, Absynth, Omnisphere, RMX, Trillian, TruePianos, EW choirs, and a lot more besides with no glitches.

I have not tried dropping tracks in Cubase 5.1.1 been having too much fun with BIAB.

My view is that you dont have to wait for more architecture its all working real fine. I think this view is shared on other forums.
