getting confused between titan z or titan black


gtx 980 is not as powerful as titan z or titan black and i am talking about to go with 4 way sli with titan black or 2 way with z
so which is good

 
You can't 4 way sli nvidia cards. 3-way is maximum. And for graphical presentation, games and whatever, a gtx 980 is way more powerful than a titan black. The only thing where the black slightly wins is computation, but for that matter, just wait until a 980 gtx ti or titan x releases with the gm200 chip. In that case, 3x Titan X would probably the best choice.

As for gaming:

Totally wrong. You can 4 way SLI quite a few nvidia cards.

To the OP. I recommend 980 SLI in 2 way. The scaling past 2 way isnt great and you end up spending a lot more money for not much more performance. Best option is to way for the big Maxwell chips (the Titan/780ti etc replacement).
 


so should i go with titan z 2 way sli or 980 2 way sli
 


Titan Z SLI will perform better as that would be 4 GPUs, but would require a lot more power, create a lot more heat and cost a ton more.
