If I understand this properly (and perhaps I don't) then many PC games run just fine on 8GB, possibly since the GPU has the textures and whatnot offloaded to it. Not many games would need much more than 8GB pure game process data in memory at once. Furthermore the bottleneck of games performance is rarely the amount of RAM, so performance went elsewhere.
