Priced at around $350, the new GeForce GTX 285 is in a league of its own, meaning that ATI has no direct competitor for it. That doesn't guarantee a good value, so it will be interesting to see if the extra performance offered by the GTX 285 justifies the $150 premium you will have to pay over a GTX 260 or Radeon HD 4870, or perhaps if it's worth spending even more on a dual-GPU 4870 X2 or GTX 295 that sell for an additional $100 and $150, respectively.

The particular Asus card that we are reviewing (referred to as ENGTX285 TOP by the manufacturer) should deliver a little more performance than your typical GeForce GTX 285 considering it's a factory overclocked model. This may also translate in a higher retail price, likely in the $400 ballpark.

Our performance comparison will put this Asus GTX 285 graphics card against ATI's top offerings, the original GeForce GTX 280, the GTX 260 and the dual-GPU GTX 295.
