it's certainly an improvement, but as to whether you are able to utilize it & notice any gains depends entirely on the applications you are running. if it's just used for some web browsing, the occasional old game & email i can't see any benifit. but for new & upcoming gaming titles i can certainly see a benifit - how much of one i think depends on how far you already have the 955 pushed & how far you are willing to push the 3570k.
