Titans aren't really optimal for gaming, SLI 780 Ti or 295x2 would be more cost effective.
I still don't see a reason to get AMD CPU for high end rigs tho..
Razer products are pretty awful. Blackwidow got chinese Kailh switches instead of real German Cherry switches and overall quite poor build quality. Deathadder is pretty good, but quite pricey for what you get.
