Had to limit across the board, using the nvram command inside of OS X. Of course it reads values in MB not GB so after typing it in as 64 the machine could not boot any thing AT ALL. I;m now in talks with Parallels support testing software for them (they never had a machine with this much resources).
I have learnt more about Apples Firmware these past 3 days then I ever wanted to.
The whole setup came to about $14,000. 3 Monitors, 128GB of RAM, two ATI video cards, 1x 480GB SSD, 1x 240GB SSD, 1x 3TB HDD, 1x 1TB HDD and a touch pad. OH and an extension cable for one of the monitors cause apple reduced the monitor cable length by about 700mm from the previous generation of monitors and of course one monitor wouldn't reach.
As for the day to day function of the machine one SSD is for OSX Lion one is for Windows 7, I currently am running the windows bootcamp via Parallels7. I am playing Star Wars the old republic on full settings in full screen, with media playing on another monitor, browsing the web on the 3rd and shifting between spaces of Skype chats, terminal windows and other virtual machines with no performance hit.
I am one happy little kid.
