Most Start: - Windows 8.1 in 45 sec. - Adobe Cs6 in 50 sec. - Open Office in 15 sec. Correct graphics card: - PC ProLite E2382HSD (Amazon purchase) - Use in the "Media Center" on TV Panasonic HDMI 106cm Installed Memory: - 1 Barrette 8GB DDR3 - 1 free slot * * Lenovo site: "The maximum amount of RAM for the Lenovo 16GB of DDR3 is H530s 1600Mhz (2x8gb)." I give the 5th star to Lenovo for configuration because other manufacturers such as HP, (my old PC 2) the maximum is 4GB (4x1gb DDR400) BUT sold with 1gb divided into 2 pairs of 256mb, so to upgrade the memory, this requires you to replace EVERYTHING! (I do not know these days, HP practice again this obsolescence upstream policy)
