Render movies at a fraction of the time (quad core vs dual), and have it sit under my desk while I leave my room with my macbook air sipping my coffee in my den watching a HD movie on my 52 inch TV.
Wanna compare what your experience would be like walking around with a laptop at 80-90C on your lap while it's incredibly slow trying to render a movie while trying to surf the internet and trying to stream a HD movie to your tv?
We both paid the same amount.
How about an overclocked i7 6-core PC vs a $5000 12-core 2.66 ghz Mac Pro. In alot of tasks, this regular i7 will blow away that Xeon CPU since Core speed > number of cores in most tasks due to how poorly multicore support is optimized. ( some cores can be maxed while other cores do nothing, so core speed is more valuable for most stuff )
And at rendering movies, if the 6-core i7 PC is clocked at 4ghz+, it's a close race
Xeon CPU is really for server imo. Why do you need error checkings for home use? Those types of errors never happen in practise anyway.
