The premium-class products do not find the game much of a test. The Radeon HD 6990 catches up with the GeForce GTX 590, but we don't know if AMD's Gaming Evolved program has anything to do with that. The average frame rate is never lower than 70 fps, so you can enjoy the game at any resolution, including 2560x1600 pixels, with either of the two cards. By the way, since each card is in fact a multi-GPU subsystem, we can say that the Catalyst and ForceWare drivers can already effectively run this game on multiple GPUs. That’s good news for owners of CrossFireX and SLI platforms.
As for the single-GPU premium-class graphics cards, the Radeon HD 6970 is just as fast as its opponent GeForce GTX 580. They deliver high performance in the Full-HD mode but you have to disable MLAA to play comfortably at the higher resolutions. Subjectively, a speed of 50 fps or lower is not sufficient to kill an enemy with an accurate headshot or hack a computer before the counterattack.
We are witnessing a fierce fight of the two graphics architectures in the midrange price category as well. This time around the GeForce GTX 570 leaves the highly popular Radeon HD 6950 behind by about 10%. Each card is capable of copying with the 1600x900 or 1920x1080 load, but the luxurious 2560x1600 mode is unplayable unless you lower the graphics quality settings.
The Radeon HD 6870 vs. GeForce GTX 560 Ti fight is no less exciting. The GTX 560 Ti wins expectedly but the more affordable HD 6870 looks good, too. Each of them keeps the frame rate at a barely playable level in the Full HD mode, so you may find the game getting somewhat sluggish in action-heavy or graphically complex scenes. The affordable Radeon HD 6850 is inferior to the other cards in this category and cannot run the game smoothly at 1920x1080.
Once again we see AMD and Nvidia solutions end their fight in a tie. This time around these are the Radeon HD 6770 and GeForce GTX 550 Ti. It takes 60 fps to play a first-person shooter comfortably, but the mentioned two cards can’t deliver that much even at 1600x900. You'll have to disable full-screen antialiasing or a couple of special effects, especially if you want to perform achievements like completing the game without setting off any alarms.
The weakest products in this review can’t notch even 30 fps. Belonging to the entry-level market segment, the Radeon HD 6670, GeForce GT 545 DDR3 and GeForce GT 430 cannot make the game playable unless you lower the graphics quality settings.
