Bottleneck? You're being sarcastic right? What you have listed is overkill unless you plan on running EVERY current game at max settings on a multiple monitor setup and record it. Even then you could lose half the RAM and the sound blaster card unless you have speakers much better than PC speakers.

There's always a bottleneck. There's always one component that's slower than the others. With the parts you've listed, it'd be a pretty high limit and you'd never notice it -- except for storage (your hard drive) unless you put in an SSD.

Well, aside from the fact you didn't tell us which GPU you'll have (a gtx titan is not a GPU model) there is pretty much NOTHING that will ever be bottle-necked by anything else you have. The only possible way you might encounter a bottle-neck is if you run quad-SLI GTX 690's!!!!!!!!

i think of curiously large. i do no longer think of you will need an 850W PSU although. a minimum of 450W is counseled, so i'd think of something over 550W is overkill, till you're making plans on going SLI at last.
