I think the Ferrari is about as fast as portable (~6lbs, 15.4") gaming notebooks come today. So far I think it beats any other ~6lbs, 15.4", X700 notebook due to a very fast stock clocked GPU. Now this is with default DDR 333MHz.
I'm just saying to get the most out of the Ferrari 4000 I would consider 2GB DDR 400MHz to get it maxed out in performance so to speak. I guess an ML-40 could always help even more, I just like the idea of maxing something that's already fast
even if not needed obviously.
