Is amd cpu and nvidia graphics card a good solution for gaming

til now i had 3 rig with amd cpu and nvidia gpu and they all worked fine

Now iam thinkinh of using amd fx 8350 with gtx titan 

I use my computer only for gaming

It would work fine maybe a 690 instead?   For more performance 

FX will bottleneck the 690 (not massively) but enough.

Not sure how Titan will fare with FX..

it's not a case of brand, it's a case of product performance and use case scenario.
