Having just bought Deus Ex Mankind Divided my present graphics card is a disaster (was OK for Thief, Dishonored, etc) but I need to get a much better one for a 1920 x 1080 monitor (the CPU etc. is fine - running Windows 7 64 bit) but the bit I am unsure about is the graphics memory.
I think that 2GB isn't a really good idea so there are three basic options (3GB 1060, 4GB various - GTX 970 possible - and 6GB 1060) as I doubt that 8GB is really needed.
I know that this is really crystal ball stuff but to get a useful life until I change to Windows 10 - probably in 3 years time - which memory option would be sensible
I would prefer to stay with Nvidia to allow graphics card switching with ease if I hit a problem
