I really don't think it's the video card because I have dual card which mean three times the handling capability, but it still crashes when push come to shove! However, every bit of extra money and power you can put on the machine would help. Quite frankly, I don't think the technology is up to par for what we do. We are so abusive when it comes to power. I worked on 3ds modeling and rendering a lot, so I know. Don't believe advice from engineer and or computer tech that say: "you are buying a Ferrari, but only drive 25mph." In that analogy, I am buying the fastest car and blew up the engine on OD all the time if I am not careful.
Back to the point of avoiding crashes. BE PATIENT WITH VW... PLEASE!!! It saves you a lot of times and headache in the long run. "WHENEVER YOU SEND A COMMAND OR PERFORMING A TASK, AND VW IS CACULATING, DO NOT CLICK ANYTHING ELSE... JUST WAIT... BECAUSE WHEN YOU CLICK SOMETHING ELSE, VW CRASHES". It happens every time. I am learning it the hard way, but I am learning... The amount of crashes I have reduced from about once every hours in a course of eight hours working session to almost "once in a full moon" when I learned to control my level of anger and impatient... LOL...It does save time in the long run w/o crash. One more thing, VW seems to like the MAC platform better for some reason.
