Official system requirements

[sg1221]

With all this emphasis on computer hardware we also need to realize that if
you have 3 different people with identical hardware , you will most likely have
3 different performance results when they play a game. The OS , software running in the back ground , the driver updates...etc will all have a big effect on the game. So you might feel like you have a killer machine but when you see
one of your buddies with a lesser machine getting better frame rates than you ,
with the same eye candy you'll be miffed.
The bottom line ...
System spec's though somewhat helpful, are very hard to predict.
