From what I can see, the processor was not maxed out, but it may still be the bottlneck?
Fastest = Intel Core i7 870 2.93 Ghz, 8GB RAM
Slowest = Intel i5 M460 2.53 Ghz, 6 GB RAM
Maybe these are ancient by today's standards? I tend to need faster disk speed and CPU power isn't a high priority for me. That said, I have been thinking about upgrading both desktop and laptop. The setup time on a new computer takes such a long time (may configurations) that I try to avoid this until necessary.
