I know this question has been asked and answered by many, but I just have to ask again myself.
I'm looking to upgrade my system and wondering how the following would effect C7 Pro.

• I currently have an Intel Core 2 Duo (2.33 GHz) and want to upgrade to a Core 3 Quad (2.4 GHz).  Besides faster rendering, what advantages might this have.
• I currently have an NVidia GeForce 8500 video card.  Would upgrading this be of any use.  (I'm not a big gamer.)
• I currently have Vista 32-bit and toying with the idea of going to Vista 64-bit.  I realize going to 64-bit will allow all of my 4 GB Ram to be used, but would there be any other advantage to C7.  (I've recently activated the 3 gig switch in Vista-32, just to see if there's any improvement, but haven't noticed any changes yet.)

Thanks for any input!
