Quote - > Quote - raytraced display mode and simulations gonna mean people are going to be very unhappy with their current video cards, me included. Im glad I wasnt lured into buying PP2012 when they had it on sale.

I didn't see anything that said either were GPU based, so it's your CPU and available RAM that are likely most important there. 

OpenGL preview is GPU based and has been further optimised in this version so it could work better than the current version on the video card you have now.

It does say under the system requirements that a "recent NVIDIA GeForce and ATI Radeon required for advanced real-time preview features". So, yes, you will need a modern graphics card for these features (raytraced preview and real-time physics I assume). I have a GTX 670, so I should be fine.
