Conclusion: ATI's Radeon HD 4670 was already the best card under $80 (currently around $70) but Sapphire has added even more value to it with GDDR4 memory and silent, superior cooling. If you have your eye on the Radeon 4670 this card is definitely one of the best and probably the fastest.
Summary: As you can see from the performance graphs I feel the 4670 preforms well for its mid range £60 price. I was impressed with its results in all of the tests, coming in just behind of the more expensive 9600GSO, as you would expect.
Pros: Good performance, - 512Mb of DDR4 RAM, - CrossfireX Ready, - Low power consumption, - Quiet fan and good cooling, - HDMI with 7.1 audo port, - Affordable price
Cons: - Not suitable for heavy DX 10 gaming, - Takes up two card slots, - Lots of competition
Summary: As I've said before, the Sapphire HD 4670 is a card, that's designed and aimed at the average gamer and mainstream users. The performance is a lot lower than its bigger brother, the HD 4850 ... but then again, that's not really a fair comparison.
