I found a site where you can calculate your benchmark score and FPS... it gives you a good idea of what every cards performance would be. The cool thing is that it normalizes the data based off of your current graphics card score. So, if you can tell what score or FPS you are getting from the benchmark (or beta), it will pretty darn accurately tell you what your score/fps would be with every card. You can also input benchmark data. This thing is sweet. It shows the 5970 out front, of course.
