Unfortunately this is only steam stats. We have no idea if gamers are leaving to play on Origin or Battle.net so we honestly don't know if it dropped or not. Would of been awesome to see Steam's player count in the same period of time.
Regardless Nvidia seems to have a lot to lose once RX Vega comes out. Will be the first GPU that can actually compete in a very long time. Their monopoly may be coming to end soon.
As for CPU stats. Doesn't mean much to me. I run an I7, but holding out for threadripper. I can't stand price gouging intel anymore.
And before any fool starts kicking and screaming fanboy, these are my stats.
