Poor analogy, at least on the BMW 1 series front-- the 1 series borrows an engine from the M3 and defeats its own big brother (3 series) in 0-60 and in horsepower, in a lighter package. It's a serious sleeper of a car.
I don't get why that guy was complaining though. I mean, they both support the same thing. It's not like you were claiming the Macbook could do something it couldn't.
Well, how about an Xbench score of 171.76 at 2.4 gHz? 😀 This puts it up with the Mac Pro - a bit higher than Apple's quad-core, I think. It took about 3 hours to put the hardware together, but I could do it in an hour or less, now.
Wow. I just overclocked the cpu to 3.2 gHz and my Xbench scored jumped to 217. I just did a 2-pass Handbrake transcode for Apple TV (2500 bit rate H.264, AAC and AC3 audio) and it did a 1:55 movie in 55 minutes. Highest core temp was 66 C. It's now idling at 45 C. Remarkable. I should have built this computer a long time ago.
