My company set me up with a Intel E6750 (2.66 GHz) dual-core, 2 GB RAM, 64-bit Vista, and a powerful 1GB video card (ATI FireGL V7350). However, after importing a site grading file, it was really sluggish. So I worked on my laptop (not nearly the powerhouse of my work pc) to get the file to where I wanted it, finishing up at 47MB. When trying to edit on my work desktop, orbiting posed no problems, but drawing was very sluggish and caused my pc to freeze on a number of occasions. I think that if my card would not try and render absolutely everything (must be cocky with it's 1GB capacity) and I could tune down the graphics specific to sketchup, I would have no problems. I've already configured Vista to minimize what the OS requires, though I don't see a way to configure my card's settings for specific applications. Any thoughts?
