ATI Radeon 4890 1GB
The recently introduced ATI Radeon 4890 is essentially the cyborg cousin of the Radeon 4870. It is bigger, stronger, and faster than the Radeon 4870, but is also the same in many underlying ways. Considering the success of the Radeon 4870, both commercially and critically, this should be considered strong praise. The card's insertion into the market was obviously meant to help ATI compete more effectively in the higher price brackets as the Radeon 4850 and 4870 had their prices cut, but the Radeon 4890 has also been quick to be put under the price axe. It is now possible to grab a Radeon 4890 for about $200 bucks.
The performance of the Radeon 4890 is about what would be expected. That means anywhere from ten to twenty percent better than a 4870 depending on the game, which translates to a video card which is capable of providing beautiful graphics at nearly any resolution in nearly any game. Even folks with 30" monitors will likely be alright with this card, although extremely demanding situations, such as Crysis or Fry Car 2 at 2560x1600 resolution, could overwhelm it.
While the performance of the Radeon 4890 is neck-and-neck with Nvidia's competing card, the GTX 275, the Radeon 4890 is currently a better recommendation thanks not only to a marginally lower price but also a surprisingly low GPU temperature under load. The Radeon 4800 cards were known for high temperature when the debuted, but that trend has apparently been reversed. While any card put on the market today should work without trouble at room temperature, the extra headroom is nice to have for warm summer days.
