Is it worth it to upgrade to a X99 computer?

[Newbbuilder11]

I have a Asus H81M-Plus Micro ATX board with a I3-4130 and a R7 260X. I plan to upgrade the CPU and GPU of the system to a I7- 4770 and a R9 280X for some let's plays and streaming. The X99 looks really promising and i might consider just upgrading in general. Is it worth it?? Or should i just stay on my path. Thanks!

Look at the 4790 and a H97/Z97 motherboard.No wish for the ability to overclock?
The other possibility is imo way to expensive for what you want.
