[citation][nom]someguynamedmatt[/nom]Meh. I'm perfectly happy with my little Phenom II quad humming along beside me. It's reliable, snappy, and it gets the job done. Maybe for someone who wants nothing other than bragging rigbhts, these will be worth it. But to people like me, being able to render a 3D layout in Blender or a video in After Effects 30% faster just isn't worth $1000.[/citation]
A 30% reduction in render time is quite significant, and while that on it's own might not warrant paying 5-10x more (even for pro applications), I think you're also vastly underestimating the performance of these upcoming Sandy Bridge-E processors.
The i7-990x, a six core processor based on Intel's previous gen architecture already outperforms a Phenom II x4 by quite a bit more then 30% in the applications you mentioned. Especially Blender, where the performance increase is probably much closer to 2x. And that can definitely be worth the price premium if the extra performance is needed and put to use. It may not make a lot of sense for the average user or gamer, but I think to suggest that bragging rights is the only reason anyone invests in a high performance processor is a bit ignorant.
