Hypothetically, with these new memory architectures, you could get the best of both worlds. Best case, you get a huge speed up if everything fits in the high-speed RAM, worst case, you fall back to the "old" RAM. Side note, while Apple charges ridiculous prices for their upgrades, Mac Pros are actually some of the more ""reasonably priced"" computers comparatively. I've looked at HP and Lenovo's equiv. workstations, and you pretty much get screwed by everyone at that scale. My desktop can take up to dual 128 GB sticks but one stick costs over $1,000, so I'm stuck with my 32 GB stick :( ... OTOH, it's pretty insane you can get 128GB of RAM for $1,000 nowadays. I remember when 8GB was a lot and cost several hundred. Time and miniaturization go on I guess...
