A few personal thoughts:
1. The 2.93GHz costs $470 more than 2.66. I doubt that very many of us can tell the difference without a stopwatch.

2. I don't know about running AB, but in many published speed tests, Vista64 takes about 50% longer than XP64.

Thanks. I was looking into i7 based-PCs. But aren't all i7's quad-cores to begin with? And apparently the OS sees an i7 as 8-core due to the way it's designed.

Dell seems to have a good deal on i7 XPS desktops at 2.93 Ghz
