"It's safe to say a large part of the [X775's] battery life comes from Nvidia's Optimus technology which automatically detects when the notebook isn't playing games or running graphics-intense applications and switches to the Intel integrated graphics to conserve battery life."
"The Just Cause 2 benchmark shows that this test is no match for the G74SX-A1 and its GeForce GTX 560M, as the notebook easily posted playable frame rates at all resolutions tested, even at 1920X1080 native res for its LCD."
"[The MSI GT683R’s] GeForce GTX 560M GPU delivered very playable frame rates, even with the eye candy dialed up. On our Just Cause 2 real-world gaming benchmark, it gave us 40.4 frames per second (fps) at 1,366x768 resolution, and 29.4fps at its native resolution of 1,920x1,080, both of which show that the GT683R can handle this demanding game without stutter or noticeable lag. Its Far Cry 2 scores were even better; it turned in 43.9fps on the DirectX 9 test and 59fps on the more demanding DirectX 10 test, both of which were run at a resolution of 1,920x1,080."
