The reality of the situation is that any Quad core and above from either manufacturer arnt really going to seem any different in the real world, your graphics card is where you will see a difference with either manufacturer in games, your Ram/ssd/Hard drives are where you will see the major difference in video editing/rendering/3d modeling, but if you were hard core in to either of them youd be getting custom workstations with 50 processors and 10 ssds in raid.It just isnt the same as 10 years ago where cpu made a huge difference, hardware has accelerated way past software in 99% of the cases.Put out all the varieties of quads and 6 cores in different workstations and nobody would be able to tell the difference in gaming if they had the same gpu and ram, same with browsing and day to day stuff, and the rendering wouldnt be noticeable unless you are sitting there with a stopwatch.

I play pc, wii and 360 all on 120" 720p projector, once you start playing on a screen that size its near impossible to play on something smaller.
