Re: Direct X11 looks to be another failure(implementation wise)
There isn't enough equity for developers to produce full on DX11 games built from the ground up. It is consoles that are holding PC games back and im afraid untill we see the next gen consoles we will be stuck with DX9 esque games untill then. Once it is feasible for developers to produce better looking games (when the next gen consoles are out) then we will see better looking games on PC that make use of todays GPU's.
Conclusion: Absolutly pointless to upgrade GPU's every 6 months unless you want to increase your E-Peen.
