The dude reckoned that no consoles launched that where more powerful than gaming PCs. Which is nonsense. Not talking about CPU number crunching for spreadsheets, but about gaming specific performance.
What PC in 1987 had better graphics or audio than a PC-Engine? PCs at the time were still rocking CGA/EGA, with VGA coming out later that year. Even then, PCs were rubbish at 2D graphics, lacking the dedicated hardware to push sprite about. Sound cards didn't exist yet. Soundblaster cards came out in '89.
And the NeoGeo blew away PCs for gaming. The sprite scaling pissed all over the abilities of PCs at the time. Compare any early NeoGeo game to something like Catacomb 3D, which was state of the art PC game at the time.
SNES and PS1 can be argued one way or the other, but I'd argue towards the consoles having better gaming performance. Everything changed mid-way through the PS1 era, when discrete 3D accelerator cards arrived. From that moment on, PCs have always been ahead of the curve. But it wasn't always the case.
