This will sound like I'm complaining, but it's just an observation - now that I have both computers running, I find that they are not equal and that one is not necessarily better than the other. The new one is faster, but the old one runs more programs that I've come to depend on.
Anyway, both systems are running, though there are some things I have to do yet for both computers. I'm not sure how they will both run or the setup I will use, but I think I may go back to using the older one full time and the newer one for certain applications. Again, I'm not sure yet, but that's where I'm leaning. I fear change, but there are also practical reasons.
The good news is that with four cores, the new computer is kicking some serious scientific posteriors in Seti@home. Wooo! I'll fix the counter on this page shortly.
