I recently acquired a new Macbook Pro 17" with 2.9 Intel chip and made an E-FIX mac desktop. Out of pure geekiness i wanted to see how their performance compared, so i used xbench software to compare the two.
Here are screengrabs of the results:
MBP17" 2.93Ghz Dual Core Processor

Custom Build QuadCore, 8gb Ram, 512mb Graphics Card:

Both are at about the same state in terms of program loading, the MBP has only one HDD so it cannot perform well in that department, but i have lots of FW800 drives so it's not a big deal.
I am a little dissapointed by the CPU score for the Quad, i will try t find out why that is so in the near future.
Maybe others can post how their mac performs so people who are thinking about getting a mac can see the differences.
