HardOCP compares the image quality and gameplay performance of several of NVIDIA's and ATI's latest graphics cards in BioShock 2, you can check it out over here.
For this evaluation, we are using a smaller lineup than usual, for some good reasons. From AMD we have three video cards. We have the ATI Radeon HD 5870, the Radeon HD 5850, and the Radeon HD 5750. From NVIDIA, we are using the GeForce GTX 285, the GeForce GTX 275, and the GeForce GTS 250.
For this evaluation, we chose to exclude the GeForce GTX 295 and Radeon HD 5970 for a simple reason: redundancy. The GeForce GTX 275 and GTX 285 can already play BioShock 2 at the highest in-game settings, so adding the GTX 295 would enable us to use a slightly higher AA setting than the GTX 275 and 285. Then, the Radeon HD 5870 can play with extremely high framerates, but since AMD’s drivers do not support AA in BioShock 2 yet, there would be no headroom to enable higher levels of AA with the Radeon HD 5970.
