John,
I have been wondering that myself. I have not been able to get to my regular editing PC (an i7 8G box with V9) but have been having to make due with a P4 (single core)2.0 2G and V7 for this project. (But both have multiple 7200 harddrives). I think I will render a small portion of the project and then transfer it to a flash drive and take it to my sons computer (a quad core)and see how it plays there. It will take a couple of days, I’ll report back.
Thanks.
