I am not talking about speed or how good your graphics card is I am talking about the drivers of these cards and how the interface with programmes. Two years ago I upgraded my graphics card so any all sining and dancing Nvidia and found that it caused GoLive CS to crawl. If you dropped a picture into a frame it would take two minutes load and if you scrolled down the page the same thing happened. I phoned Adobe about the problem and they said it was a known problem but they had no solution for it. As at that time most of my income came from web work I had to refit the old graphics card to regain the speed. All that i am saying is that this could be the problem as there have been only a few people stating that Extreme crawls.
