Yeah, I'm a little surprised to see PC initially exceeding essentially a 8GB HD 7850 that is PS4.
I guess I thought unified 8GB would provide more benefits. Most enthusiast video cards on PC probably are still around 2GB VRAM.
But then you remember the next gen consoles are "really" only 5GB machines, which has to be divided between CPU and GPU, for one thing.
The PS4, the console that shot "high" this gen, is still really quite low, as evidenced by it's 140 watt max power draw.
I figure once the 1st party wares from PS4/XB1 start to show-up next year and beyond, we should start to see some amazing graphics, very comparable to the PC. I just don't see multi-platform developers doing that, at this point and time.
