Dont want bottleneck when i upgrade to the gtx 1070, help?

[Elfb]

I want no bottleneck at all

What hardware do i need to change and what do u recommend?

How much bottleneck will it be if i only change the graphic card?

I have not changed this prebuilt computer anything.

The graphic card i have now is somthing in the AMD Radeon HD 7900 Series.

Specs:
Motherboard=GIGABYTE 990XA-UD3
CPU=AMD FX(tm)-4170 Quad-Core
RAM=3*4gb(in total 12)

If in need of more specs to help, then pleace tell me!

CPU and Motherboard definitely need changing i would say to something like an i5 6600k (if you get the 6600k you will need DDR4 RAM too). What Power Supply are you using at the moment?

i am using a proseries xfx 750W as power supply, is the GIGABYTE GA-Z170-HD3P (rev. 1.0) LGA 1151 Intel Z170 HDMI SATA 6Gb/s USB 3.1 USB 3.0 ATX Intel Motherboard a good one?

Yep that PSU and motherboard are good.

As already said you will need DDR4 RAM. I suggest 2x 8gb.

Yep that PSU and Motherboard sound good, as @RobCrezz said 2x8GB 2400Mhz+ RAM would go together with the i5 and a 1070 would make a very nice system.
