GeForce 605 1GB Review
GeForce 605 1GB is an entry-class GPU part of the 600 Series released by NVIDIA in 2011/2012.
It seems it's still based on the 'Fermi GF119' architecture and therefore just a renamed GeForce GT 510 with exactly the same specs and so the performance is exactly the same.
There are two versions available, whereas one features 1GB of video memory and the other only 512MB. This is the 1GB version so the performance is only slightly better, since the 64 bits Memory Width doesn't let the GPU go very far with large amounts of memory.
Very demanding games (e.g. Metro 2033, The Witcher 2) might be unplayable, even at the lowest settings or only playable with unattractive resolutions while demanding games (e.g. Crysis 2, Skyrim V) should playable at low settings smoothly.
