I dont' have butt load of money to burn wanted to save some money and bought the lower end dual core, but before I knew it I was spending more and more money to try different stepping just to hit the prime stable @3Ghz mark, If I had to do it all over again I would definitely jump on the 4600 and be done with it. For my next upgrade I'll definitely get the higher end stuff instead of keep buying the budget stuff in hope to get lucky
