This is more of me wanting to hear some opinions on the value of dx11 in today's market. There are currently very few games which incorporate dx11 specific features such as tessellation. I realize that this is a nice feature to have, and can improve the quality (that's what I've been told) of the game. However, there are many games without dx11 that have great if not incredible graphics (e.g. crysis). Seeing as games with dx11 do not necessarily contain "better graphics" than dx10/9 games, why would one want to spend the extra money for a dx11 capable GPU? Supposing you have a high end ATI 4000 series GPU (maybe 4890, or 4870 x2), what reason would there be to upgrade to a comparable 5000 series card? Aside from details such as power consumption, noise levels, and temperature, I can't think of a purely performance based reason to upgrade. Looking forward to your opinions!
