As an upgrade from the M11-S3420, the more expensive Tecra M11-S3430 trades in its predecessor’s entry-level Intel HD graphics for an advanced/discrete Nvidia NVS chip better geared for processing movies, photos, and memory-intensive games. Plus the M11-S3430, which is in fact the best of the series, includes a slightly faster Core i5 processor, 3GB of DDR3 RAM, a 320GB SATA HDD, and fast wired/wireless connectivity options like Gigabit Ethernet and Draft N wireless.
