I have X2 4200+ going at 2.9GHz per core up from 2,2Ghz (HT is 4). VERY pleased with it. Thats about 33% rise in perf sue to overclocking.
I want to add more juice and I could afford X2 5600. This seems to run standard 2.8GH'z per core.
My question is :
Will I be able to get 30% overclocking performance increase from a 5600 ? or is there some kind of invisible GHz barrier that I will hit no matter what processor I buy.
