When testing Aliens vs. Predator at 1920x1200, the default GTX 660 Ti averaged 40fps (Gigabyte's solution was 2% quicker), which worked out to 5% slower than the HD 7870, 25% slower than the 7950, and 22% slower than the GTX 670.

In Metro 2033, the Gigabyte's GTX 660 Ti was 3% faster than the stock speed, which placed 7% ahead of the HD 7870 and 12% behind the HD 7950 while being only 10% slower than the pricier GTX 670. Also of note, the 660 Ti was faster than Nvidia's previous-generation single-GPU flagship card in this test.
