Not necessarily. Just try comparing launch titles on the 360 and PS3 to games that came out this year. Developers can get a lot of mileage out of optimizing for a fixed hardware setup like consoles, whereas your PC graphics card will generally always have the same amount of performance.
These consoles will probably peak more quickly than the last console generation did, as the architecture in both is pretty straightforward. They won't require voodoo magic to get the best performance out of them like the PS3 did.

The "next gen" has been on PCs for a while now. The Witcher 2, Battlefield 3, Crysis 3, Tomb Raider, etc. What MGS5 does may be relatively on par with those, but it's nothing really new or special.
All I can do is compare 720p video trailers to 720p video trailers and I'd say these announced games look better than anything PC has put out so far.
And remember that high-end graphics cards can run all those games with higher AA modes and resolution -- 1440p and above. With 8 GB of DDR3 memory, only marginally faster than the GDDR3 that was in the 360, the Xbox One will probably soon run into a memory bandwidth problem if not a memory space problem. The PS4 should be spared this problem for a while, as Sony went to the extent of putting 8 GB of fast GDDR5 memory into the console. As good as MGS5 looks on the Xbox One, it will look quite a bit better on the PS4.
Well that explains it. You haven't actually
seen what a PC game at full blast can do in person. Your graphics card is a good deal weaker even on paper than the chip in the Xbox One, and you can't even use DirectX 11 features.
