I would say depending on what kind of game Genre you play. For me, as an avid First Person Gamer and one that only plays the Campaign, I see no reason why I should waste my money, at least not at the moment.
I will try to explain what I mean... as you, I have a GTX260 as my main GPU and a GT9500 for PhysX only.
The majority (if not all) the latest Shooters (many of them now 3rd person crap) are nothing more than Console Ports, some of them crappy and unoptimized (all Ubi Shooters make this list
) and some of them optimized (CoD's, Crysis 2) but still... they are all made with DX9 technology and even though I did not play Crysis 2 with the HUGE patch for DX11, I saw it on my friends computer and I am still not that convince as my DX9 game was most excellent when it came to video quality. I may not play these game in 120 frames per second but then again, I am tickled pink when I can do so at 30 to 45fps.
Sure, I work hard and I deserve to have the latest and the greatest (or at least 2nd or 3rd shelve down
) but really... Why?
On the other side of the token, if you have the money and you feel like buying something (nothing wrong with that)... I would go ALL OUT with Newer Technology all the time so... DX11 it is!
