You may want to consider the GIGABYTE U2442 Ultra Performance ultrabook. It will come with either a i5 or i7 CPU and the nVidia GT 640m/650m. No release dates or starting price have been announced yet. It will have a 1600x900 resolution screen.http://www.gigabyte.com/press-center/news-page.aspx?nid=1127
