Planning to buy a AMD Athlon 64 X2 5600 Brisbane 2.7GHz or 2.9GHz. Does a few Hz make a difference? Is it worth to spend $13 more for the 2.9HZ processor?
Run your clock speed at 215MHz. Your HT speed will be fine at 1075MHz. And your RAM will run at 860MHz @ 1:1 ratio which should be easy for decent RAM.
You'll have a 2.9GHz chip for the price of a 2.7GHz chip + 15mins of your time.
