I'd probably buy Intel. Not because AMD is lesser, it is that the corresponding chipsets at the mainboard are not as well worked out. May be because they aren't filtered by the time factor yet, or there is not enough competition for mainboards on the AMD side, or else because AMD doesn't build mainboards to play a model. Also add that the most sofware are optimized for the Intel chipsets from the first versions.
Even with 3D modelling and rendering my time loss caused by the computers is seldom because of the processor speed. IMHO, today, stability is much more important than the advertised speeds. After a sad AMD experience I think stability is the weakest link nowadays. I find the happiness in Intel processors on Intel mainboards preferably, if not the Intel chipsets.
This may sounds like an ad. I did bought the AMD, because it was the competititor, alternative and the rare one with the cool logotype. I still think they are great processors but the things that you have to couple with them are not matchingly stout. When you face with hardware failures with the most expensive mainboards you get the hard fact.
I don't think I'd buy another AMD without a complete system warranty (software included).
