Most important hardware component for large models?
(OP)
What is the common hardware bottleneck when using large/complex models in UG? I'm trying to put together a 'test' machine at my company for future workstation upgrades. Most of our computers are running a 2.67Ghz Intel Xeon with 16GB of ram and a FirePRO V7800 (2GB). For the most part, the machines can handle smaller models and assemblies but really tend to choke once we get into larger assemblies.
I've never really seen any of our computers use anything over 8-9GB of Ram, so I assume that's not the issue. I have yet to check GPU load, but I have a feeling that it's not the problem either, but I could be wrong. I'm leaning towards the CPU bottlenecking the systems but again, I haven't run any tests to say for sure. I'm sure many people here have been in the same boat, so any feedback is welcome.
I should also note that we're using Windows 7 Enterprise and NX7.5 - NX9
Thanks in advance

One of our users said that he walks away from the machine when he needs to unhide something as it can take several minutes until it's ready for user input.

edit: So I tried loading an assembly with "use lightweight representations" checked in load options and didn't notice much of a difference. Is this something that has to be setup in the assembly components?

I'm just wondering what kind of hardware would tend to help the most in these instances. Does NX tend to scale linearly with multiple CPUs and cores? Our RAM seems to be OK. Unless multiple sessions are opened, we almost never exceed 50% used.
