My computer is quite fast, however, when I run Inventor with a large assembly, moving any mechanisms is extremely slow.
Model: MALIBAL Nine X7200
CPU: Intel i7-960
GPU: 2x AMD Radeon HD 6990 in CrossFireX
RAM: 12 GB
HDD: 7200RPM SATA 750 GB
I understand that the GPUs are not technically made for CAD, but I would expect that they would at least be able to run Inventor at an acceptable speed. Most of my projects are VEX and FRC robots, which are not any more complicated than a lot of the other projects I've seen. Thanks in advance for the help.
i7-960 = $300 good for a cheaper gaming cpu (only 8MB L3 cache)
2x HD6990 = $1500 excellent gaming gpu (as inventor uses directx, its also a great setup for inventor - Although an overkill for the cpu - the mobo has X79 chipset = vgood)
only 12 G ram (and what speed - did you get the 1066 [only average] or the 1333 [better-but not the best]) - Inventor loads a lot into ram...the more the better at todays prices, load up on the fastest you can get
7200rpm SATA HDD - inventor does a lot of file openining id go multiple raptor(10000rpm),scsi or solid state in a raid config (if you have a good server and redundancy then 2 stripped would do otherwise id be looking for a raid 5 or 10 setup)
all in all while that machine will work on inventor models ok, i would not consider that to be a 'fast' inventor pc, it would be good to take on the road, however a dedicated pc will kill it for speed on big assemblies
when I run Inventor with a large assembly, moving any mechanisms is extremely slow.
Assemblies (especially with moving mechanisms) are extreemly sensitive to technique.
Neutral format imports?
Poorly modeled parts?
I think only way to know for sure is to have someone else take a look.
I can often narrow down on one particular part causing problems pretty quickly.
A little slower method is to remove parts one-by-one and see if it makes a differnce and then undo.

make sure "software graphics" is not checked under Application options/ hardware, but use either Quatlity, Perfomance or compatibility.
