Computer for Inventor

[Garret]

I started using inventor this season and was able to create my teams robot in it but just barely. The reason I say this is because Inventor has been crashing a lot and will sometimes do so before I can save. My laptop is about 5 years old now and inventor takes about 5 minutes to start up on it and will sometimes crash if I am opening large files. My main problem is that much of the KOP and parts from the CAD library cause autodesk to give me a message saying something along the lines of "this session of Inventor is using 96% of your virtual memory..." and then before I can save or do anything it says that no Virtual memory is available and then closes Inventor. I have been working around these problems (mainly by creating "look-alike" parts to act as place holders and by limiting detail) but my solutions don't really do much.

Since I am replacing my laptop soon what type of computer should I consider getting in order to use inventor more effectively? Better yet is their some way I can format inventor so that it will run on my laptop without causing it to crash? Also is there something I can do to make inventor load/run faster?

Any advice would be greatly appreciated,
