Well it seems that my trusty old GTX460 with 1GB vram is running BF4 just fine in 1080 on high settings.
Just as well i didn't fork out a few hundie for a new gfx card just for this game.
I've only played it very briefly in MP and SP. My first impressions of it is that it plays good and looks absolutely stunning in SP mode but I think they've dumbed down the graphics significantly in MP.
Mind you I'm still running on old Nvidia drivers @ 306.23 and not the latest.
