The problem is, you can't just match hardware performance. Consoles are very optimized for gaming and games are very optimized for consoles, to make them look great, even on the relatively weak console hardware. There are even reports that game devs are artificially crippling games on PC or making them look worse, so they are a closer match to the supposedly "next gen" consoles (which is by far the most lucrative games market, hence they don't want customers thinking consoles are way behind PC). In reality, top end PC hardware is miles ahead of consoles, but there's not one game yet that runs well on a PC and looks substantially better than consoles.
