The Phenom II X4 970 takes a very small baby step over the 965, as it offer just a 100MHz performance gain while previous models have typically gone up in 200MHz increments. The Phenom II X4 970 also costs 12% more than the 965, while the best case scenario will only show a 3% performance increase. Adding to this is the fact that there is really no difference between the 970, 965 or 955 models.
