more than 8 GB memory is a gimmick, we all know 8 is overkill anyway, about the only time you would use a full 8 gigs in a consumer envireonment is running multiple instances of games, or using a RAMdisk.
Not really. You do need significant amount of memory to do liquid flows, for example, in a reasonable way even if highly simplified. Semi-realistic propagation of fire and smoke as well - there is so many things which are not done in today's games bcos of lack of computing resources and memory. For realistic environmental destruction (like, for example shooting enough holes into the wall of a building to make it collapse in a sensible semi-realistic way) you need also significant amount of memory and good amount of processing power as well. But as todays games aim at lowest common denominator and insist on being 32 bit such things are not done or if they are then at best as scripted events or cut scenes.
Besides XBOne has unified HSA like strcuture with the gpu and cpu sharing the ram pool. It's just that XBOne gpu might not be strong enough to really take advantage of more than few gigs of RAM.
As far as 8 GB being gimmic goes .. well .. depends. You can mainly game on it without issues as almost all current games are 32 bit and as such are incapable of using more than ~3.5 gigs. Ofc if you use your PC only for running 32 bit games and to browse web then 8 GB might be "gimmic" for you. Although I would go as far as to say that around 6 to 8 GB is atm already the optimal amount. If you use your PC in a serious manner tho then you will not have a problem of not using its resources. I went from 8 to 16 some years back, used it all, went from 16 to 32 GB and still used it all and wanted more and atm I'm sitting at 64 GB of RAM and I would like to have more ofc, but I can live with that amount for time being. Ofc for a game console such amount might be overkill as it will not have enough power to take advantage of such amount on regular basis.
Now if the question would be - is 8 GB something you can live with then ofc answer would be Yes. But with memory its no such thing as too much memory. If the option is there its useful to have it.
