Re: Direct X11 looks to be another failure(implementation wise)
The thing is, those $400 PC's sold at Best Buy etc *can* actually be good gaming PC's, with the simple addition of a $70 graphics card they'll deliver a far better experience that the consoles (non-exclusive titles excluded of course). $500 is completely doable for a very good gaming PC, if you hunt you can even get a tri-core AMD system for that amount even without resorting to DIY.
The myth that you need to start at $1000 is exactly part of the problem. No, you don't. People are led to believe "Gaming PC's" are this boutique item because that's exactly how they've been marketed by short-sighted OEM's. Most people simply have no idea how cheap and powerful PC's have gotten in the past few years.
