On the evidence we've gleaned, both the nVidia GeForce GTX 275 and the AMD ATI Radeon HD 4890 hold a clear advantage over what came before and are great value products, whichever you choose. As for which of the two to go for, that's less clear cut.
If you tend to leave your computer on for long periods of time when not gaming, you may appreciate the lower idle power of the GTX 275. Likewise, the wider software support for CUDA, over ATI Stream, may attract you to side with nVidia, especially if you work with video a lot - be it editing or trans/encoding. However, based on the games we've tested, ATI has the faster gaming card overall and for us that's still the most important consideration.Read full review
