The Acer Aspire Timeline Ultra M3-581TG not only has an unwieldy name, it is also carries a GeForce GT640M, the first Nvidia GPU based on the power efficient Kepler architecture.
Kepler GPU architecture is in 28nm silicon, with 384 cores running at 625Mhz and a 128-bit memory interface running at 64GB/sec-- a combination Nvidia says can handle a game of Battlefield 3 on ultra settings at 1366x768 resolution.
As for the ultrabook itself, the 15.6" Ultra M3 carries an Intel Core i7-2637M ULV processor, up to 6GB of RAM and either a 500GB hybrid HDD arrangement or 256GB SSD. The chassis is 20mm thin, and comes with a selection of ports and an optical drive.
