Nouveaux Macs Pro, Faut-il prendre l'ancien? Options

Bonjour bonjour,

Voilà, la question est dans le sous-titre. Non, non, il n'y a pas d'insinuation...

Un argument de poids:
"DO YOU NEED AN 8-CORE MAC PRO or just more RAM?
Even if four 4GB modules are found to work in the 4-core (4 memory slots), it will cost you at least $2300 as of this writing to reach 16GB. With the 8-core (8 memory slots), you can buy eight 2GB memory modules for $300. Like the saying goes,
"You never can be too thin, too rich, have too many cores, or have too much memory.""

Sinon, il y a ça que je ne comprends pas bien, si quelqu'un peut m'éclairer ?:

"Troubling news on Mac Pro memory PERMALINK
I spent most of today recoding diglloydTools to be able to characterize memory and computing performance with 16-core machines, like the new Mac Pro (8 real cores, 16 virtual cores). diglloydTools is available as part of DAP.
When is more memory slower? When it drops DDR3 memory speed from 3X (triple-channel) to 2X, which is apparently what installing 8 modules instead of 6 does in the new Mac Pro “Nehalem”. It apparently downgrades speed for all modules, not just the last two. This is preliminary based on numbers provided to me by Rob-Art at barefeats.com on his 2.26GHz MacPro using my just-revised diglloydTools."
