Summary: Overall comparison, I found that the 4670 was able to contend and sometimes overpower the GeForce cards with little effort. Except for the Radeon 4870 X2, which whipped ass on every turn and was way beyond these other cards.
Summary: The Sapphire HD 4670 is an entry-level graphics card that casual users will be sure to love. Like its midrange and high-end siblings, it offers an exceptional performance for the asking price. Another Radeon winner.
Pros: Highly affordable, unmatched performance for the asking price, low power consumption
Cons: 128-bit memory interface, struggled to run Crysis
