Pros: Great the casual user
Cons: Exactly the same as previous models. Financial loss for overclockers
An average, or even beginner overclocker can easily OC an 530 or an 540 to perform exactly the same as this 550. The heatsinks are the same.
530 multiplier is x21
540 multiplier is x23
550 multiplier is x24
Minor FSB boost to either 530 and 540: $$$ saved.
