NVS 2100M is an entry-level business card with support for special drivers that are certified for professional applications like Microsoft Office Suite, Hummingbird Exceed, Lotus Notes, etc. It's part of the NVS Mobile Series released by NVIDIA, in 2010/2011.
Though business cards have no driver support for games, some of them deliver astonishing performance (e.g. Quadro 6000, Tesla C2075). NVS 2100M does support DirectX 10.1 but the limited Memory Bus and all the rest put together result in poor gaming performance.
Still, it should be enough to handle demanding games like, Crysis 2, on the lowest settings possible but games like Metro 2033 are probably unplayable at the lowest settings.
