The majority of PC games are pretty simplified if for no reason other than that the average PC gamer is not the PC gaming enthusiast with a custom built system that PC platform fans like to claim is the norm.
It's actually the high end games that represent the much smaller niche market with the overall PC gaming world.
Barring RTS games (really not any more "hardcore" as a gaming genre; just has a very specific appeal), most of the high end games from a technical standpoint, are typically released on console simultaneously (if not on console first).
Even FPS exclusives on the PC pretty much start and end with Crysis; a 2007 game with a 2008 standalone expansion. And with CryEngine 3, Crytek is clearly emphasizing the console market with their next generation of games.
DX11 may well bring the next leap forward for PC gaming, but that remains to be seen. A DX11 killer app has to be developed, published and be a commercial success first.
It still boils down to the DX11 games and as long as we see a significant chunk of PC gamers clinging to Windows XP, it means they aren't buying the benefits of post DX9 developments, making it pretty pointless to emphasize the benefits of the most current PC hardware.
