Mainly because when multi gpu doesn't work, the extra beef of the 570 will come in handy. Also have a new monitor and I want to dabble with 3D.
Couple of ?s. Physx support in games, do you feel the benefits are worth it? Say losing one of the pair to Physx in Just Cause 2, Mafia 2 etc ?
Also, what drivers are the current "happy" set?
You don't lose one GPU when running SLi for PhysX. The PhysX runs one one GPU, but the graphics load is still balanced across both.
I like PhysX. It's not the deal maker/breaker 3d Vision is for me, but the effects are a nice extra in games and in general anything that adds realism to the scene increases immersion.
As for the drivers, just use what's on the website now. It's pretty rare that there is a problem with NVIDIA drivers.
