Sounds like you're on the right track. I did the same upgrade about a year ago, and it's worked great. (I came from a Dual 2.0 G5) I'm on a Dual 2.8 Quad Xeon, and I rarely have processor bottlenecks until I'm hitting memory limits with VIs. The Magma chassis is invisible.

And FWIW, PT8 is a really nice upgrade, I think.
