I think the formula "performance/money" is fitted better by AMD than by Intel. If you take "performance" and "forget the money" Intel will be your friend. I myself choose an AMD Phenom X6 1090T (which can easily by pushed to be a 1100T by the way) on a ASUS Crosshair IV Formula. But a few days agao I heard Gigabyte would be more AMD friendly... I uses this mainly for rendering -- all cores can be used by Blender in parallel. Only my two cent ... you currency may vary. I DONT WANT to start a flamewar here! Its only my opinion I wanted to express :) Best regards, mcc PS: If the siftware you will use is not capable to put full load on the machine you will pay for more hardware than it is used. PPS: Hyperthreading uses unused parts of a core to run stuff which does not need the used parts of the same core. When you have 8 identical jobs running, there have to be 8 identical parts in the cores available otherwise there is nothing to hypethread. It depends heavily on the kind and mixture of jobs running on the machine whether hyperthreading is a win or a marketing joke... I myself (own opinion) feel better to have six physical cores capable of running six identical threads doing six things real parallel, than to guess, whether 4 of the eight threads Blender is showing me is /possibly/ waiting for getting access to an unused part of one of the four cores. Yes, I am an AMD friend since Intel way of "handling" the P90 floating point bug for their customers. And since this 15 (?) years this decision was ok -- at least for me. ;)
