This should be a fairly easy question to answer: I'm not a gamer, but I use dual displays most of the time (usually a 24" Dell U2410 plus MBP screen). I usually have 3 to 4 applications open in full screen and maybe another 3 to 4 open but not in full screen (one of which is Audirvana Plus - RAM intensive). I'm in the market for a new MBP 15" - High Res, but not retina. Will I be better off with 1GB of Vram or will 512MB be sufficient? My current MBP has the NVIDIA GeForce 9600M GT 512 MB and that seems to be near maxed out most days. I'm sure improvements have been made since 2008, hence my question.
