Due to total lack of any self-control and an overly generous Apple gift card that was burning a hole in my pocket, I bought the bullet and got a Hex Core today. The projected speed advantage to Sandy Bridge wasn't worth the wait, and I can just upgrade the video card later. I got the RAM situation under control and bought 3rd party (Apparently I have to toss the three standard chips when using registered? Lame), but that's about all I can afford to upgrade in this thing. I have an SSD with Lion installed in my current Mac Pro. My question is: can I just take it out and put it in the new one, or do I need to reinstall? In addition, I'm taking the stock 1TB drive in the new MP and putting it in the 1,1. I'd really like to not have to reinstall if I can avoid it. Windows 7 is probably going to Seppuku. I've actually booted my Mac Pro off my Macbook while in Target Disk mode before (PS: it takes like 30 minutes to boot), so I know it's likely okay.
