Ultrabooks and dedicated graphics are a rare pairing, especially in the classic 13.3" chassis. The Asus Zenbook Prime UX32VD changes that with NVidia GeForce GT620M dedicated graphics with 1 gig VRAM. The CPU is pure Ultrabook with third gen ULV Intel Core i5 and i7 CPU options, and our machine has the 1.9GHz Core i7 ULV CPU. The UX32VD has 4 gigs of RAM (upgradable) and a 500 gig hard drive with a 32 gig iSSD that's used as an Express Cache.
The NVidia GT620M is an entry level GPU based on the older 40nm Fermi architecture. It's not going to run the most demanding games well at high resolutions (Crysis, Battlefield 3), but it is faster than the also integrated switchable Intel HD 4000 graphics. In our video we test a demanding current title (Skyrim), a more easy going but still graphically rich shooter (Left 4 Dead 2) and Civ V to test the ultra low voltage CPU's ability to handle all the thinking that goes into a modern turn-based strategy game. In each game we show you the settings we used and FRAPS is running so you can see frame rates.
