Multi-GPU Results: Battlefield 3
Battlefield 3 is particularly problematic for AMD, so the 7970s in CrossFire don't put up a fight. Instead, GeForce GTX 770 is barely faster than 680s in SLI, while the GK110-based cards rule.
Fortunately, even at 2560x1440 and Ultra detail settings, the 770s average more than 100 FPS.
Two GeForce GTX 770s and 680s track each other very closely, both just slightly faster than a GeForce GTX 690.
Once we pull out all of the runts and frames that hammer the Radeon HD 7970s in CrossFire, frame time variance doesn’t look so bad. However, the Nvidia solutions demonstrate even tighter latencies.
