I'm in the middle of doing the same thing. In several recent threads Peter was asked what was the best way to install everything from the HD and he said if you have a big enough system drive to install it all there including all the RT's and RD's. Like you I've been running off my external HD because my old machine was just that, old. My new Athlon Phenom 6 core has a 1TB HD as well so that's what I did and my Everything Pak HD's are going to be backups. When you choose Option 3 the installer defaults to your C drive and it's automatic from there. What amazed me was it only took 7 or 8 minutes to install and copy over everything and that's just using USB 2. My new mobo has an external E-Sata port but I haven't bought an E-Sata external drive yet. I can only imagine how fast that will be doing file transfers.

I've read that Windows can actually boot from an external E-Sata drive so that's next, I'm going to get one of those drives and clone my C drive to it as a system backup.

Something else you'll like is all the other posters with quad cores or better are right. I've done songs in Biab using 5 or 6 RT's and they generate and play in 4-10 seconds. It seems RT's solo's take longer than backing tracks. 5 backing tracks will generate in about 4 seconds for me while 4 RT backing tracks with a RT solo takes about 10. 10 whole seconds, oh wow, what am I gonna to do, that's soooo long....yeah right, my old machine was taking 30-40 seconds for that.
