AMD part numbers don't reflect the actual clock speed, but rather what AMD reckons to be the Pentium clock speed that would be needed to equal the performance. So it may not be the same as a 3GHz Pentium in an individual application, but across the board you'll not see much difference. There was a time when Intel's floating point arithmetic was reckoned to be much faster than others', but I don't think that's the case any more. I've used AMD processors nearly all the way, mainly because of their value for money. Those irritating Intel adverts that we get on TV in the UK are another good reason. :) The memory and disk space will both be handy for Poser use as well. Make sure you can add to both of them when you need to. :)
