I need help please.

Ok, I just dl'd the new 2011 BB/RB but have not yet dl'd any new RT's. I have been running 2010 on my c drive but I have BB/RB 2010 with all my existing RT's also backed up on the usb drive they came on.

So I could go ahead and shrink my existing real tracks and see if my old computer can handle the new way right? I'm still using my Compaq Presario AMD Athlon 64 3800+ 2.41 ghz running XP sp 3.

My other question is how do I know how much cpu it's using - where do I look?

Thanks ya'll.
