EDIT: Obviously this only addresses problem 2 <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
Could be the graphics card causing the problem... Nvidia cards are not entirely direct x9 compliant - therefore if BD is using some dx9 features that the nvidia cards do not support it can cause slow down even on high end machines such as yours.
This problem is most notable on xbox ports (such as Deus Ex:Invisible War and Halo).
I have a similar spec machine to yours and I often get choppiness or low fps on games that are dx9 heavy.
For example, I am playing Far Cry - the game only officially supports directx9 (direct3d) and I often suffer from lag in the wilderness areas (and I am by no means on the highest settings). So I turned on the unsupported OpenGL mode (does not use dx9) and now the game flies and I can turn all settings up to max with no signifficant hit on my fps.
Anyway, I suspect that this is the problem.
