Photoshop filter comparisons or other CPU tests are great when comparing macs/peecees...if you are a SPEC guy. But there are many other reasons I go mac. Design, quality, function, style, performance, durability, OPERATING SYSTEM. These are all categories that apple arguably kills every other computer company. I'm a MAC guy. I hate windows (I own two windows machines so I know both). OSX kicks ass. So I don't care if some dell peecee can do a photoshop filter .0062 seconds faster than my mac (which it probably can't anyway). If it has windows then the clunky, irritating OS interface will slow down any productivity a faster processor speeds up anyway!
