Excerpt: The ATOMIC series of cards is one that we really do get excited about when it comes to Sapphire products. Unlike a lot of other companies who overclock, Sapphire tend to really mix it up with this particular series. We don't only see some serious clock speeds, but also something fancy in the heatsink department which always helps bring the card to a new level.
Summary: It looks like Sapphire has struck gold with their HD 4890 Toxic Vapor-X. The card offers considerably improved performance over the HD 4890 reference design and can beat the GeForce GTX 280. It does all that without being noisy, it is much quieter than all other HD 4890 cards I tested so far. It's great that Sapphire finally listened to our constant nagging: "your cards are too noisy".
Pros: Quiet, High default clocks, Voltage control support for memory and GPU voltages, Six + Eight-pin power connector, Nice aesthetics
Cons: Very limited overclocking potential, No support for CUDA / PhysX
Excerpt: ATI's Radeon HD 4890 is the latest chipset in the consistently good HD 4800 range. Both the HD 4850 and HD 4830 received Best Buy awards, and the HD 4870 impressed us too.

Sapphire's card uses the reference HD 4890 design. It's not overclocked, but it's still impressive on paper.
Summary: Resumen: Sapphire nos presenta su Radeon HD 4890, una tarjeta que con la rebaja de precio y gracias a sus excelentes prestaciones resulta ser una estupenda opción para adquirir un modelo de gama alta.
Pros: Calidad general, Accesorios incluidos, Escelente rendimiento, Funcionamiento fresco y bastante silencioso, Relación precio-rendimiento excelente
Conclusion: Uusi versio puristaa enemmän tehoja irti vuoden vanhasta piiristä korkeammilla kellotaajuuksilla. Hintansa puolesta 4890 kilpailee suoraan GeForce GTX 275:n kanssa. Pelinopeudessa nopeuskuninkuus vaihtelee pelistä toiseen, joten se ...
