Interesting. Makes sense. I'm betting that by the time I want >2GB the 4+ GB chips will be more common. That's why I went with the x64 OS version. If I didn't need to use Solidworks I would probably have preferred the new Mac - I just don't want the complication of running SW in a virtual machine - perhaps it'd work fine, but if it didn't I'd be stuck since it's not officially supported by Dassault.

Thanks for explaining that.
