In the past i upgraded my videocard to get more framerates ,but found no difference in performance overall . so i found out that my problem was the cpu was bottlenecking the whole system ,so until i upgraded the cpu i would only get the better framerates . Maybe thats your problem too! it may be your cpu thats holding the new videocard back .It would be interesting to see what the 9600 gso can do with a 3.0 Gb cpu in your system! Just a thought!
