Having an Ultrabook with a new dual core Ivy Bridge CPU is nice, but without a powerful GPU in there as well, it just won't be as much fun. NVIDIA has your back though with its GeForce GT 600M series of mobile GPUs in the new Ivy Bridge Ultrabooks from Gigybyte, Acer, and Asus.
The 13 inch Asus UX32 features a GT 620M to drive its 1920x1080 screen. Powering Acer's M5-481TG 14 in screen is a 640M LE while the M5-581TG, with its 15 in screen, gets the 640M. The U2440N from Gigabyte has a 630M inside for its 1366x768 screen, while the U2442N gets the lineup-topping 650M for its 1600x900 screen.
Naturally all of these laptops feature NVIDIA's Optimus Technology to keep your battery lasting as long as possible.
