Maybe it's me but if I cannot afford $400 for a video card I should not ever be even close to looking at a $400 card. So trying to say "oh I can pay for it through bitcoin mining" is a little weird. Especially since your power bill isn't free and the 7970/7950 are power hogs compared to their Nvidia counterparts. For me, everything is about performance in games. If I wanted my PC to make money I'd be doing Photoshop and Illustrator all day, which I do at work. Then you wouldn't need these DX11 cards. I don't know if I'm way out in left field here, but wouldn't most people be interested in any of these cards specifically for playing games with in the first place?
