Sure you might have 16 GB of DDR3 for your system and 3 GB of GDDR5 for your video, but it’s not the same as the PS4′s unified 8 GB of GDDR5 clocked at 176 GB/s for system and video.
That difference is not necessarily a good thing for the PS4--at least not initially. Game developers aren't used to coding for so many cores and rarely (even on inefficient PCs) use so much memory bandwidth, so it could be a while before they can take advantage of the extra headroom. And it isn't yet known how much of that processing power and memory is reserved for other system functions. And multiplatform development will, of course, keep everything a bit underpowered anyway.
In terms of what we've seen so far, the PS4 looks to be pretty much equivalent to a current PC with moderate-to-high graphics processing. I'm sure that that will get pushed further as the console progresses--especially in first-party games--but it won't be the same visual leap that we saw this generation. We're hitting a cooling off period in PC GPUs, so we could be entering a 2-3 year period with relative visual parity between PC, PS4, and Durango. That could lead to some really amazing multiplatform games.
Regardless, the real selling points of the PS4 won't be in visuals and raw processing power IMO. It will be in system features, exclusive games, and network offerings.
