You can use the tool on this site to calculate your FPS in Starcraft II. You have to normalize the data based off your current card and FPS so it is accurate for your PC, but you can also input benchmark data. Pretty sweet if you ask me... basically it shows how much my 9800GT needs upgrading. Here
Actually you can just play the game (SC2) and have the FPS in the corner of your screen. There was a key combination you could press to get the FPS to appear and disappear. I forget what it was. But it should be there in the retail version.
No but this thing will tell you which card you need to buy to improve your FPS. It will also tell you based on price the best one you can afford for the $$. Its awesome... almost as awesome as this game.
Which is very useful for people who want to figure out if they can play and thus should buy the game.
lol Yea.. if you are impatient like me, you always want to know which card you need before the game actually comes out. Wheres the fun in waiting?
