How powerful will my PC be? Will it be as good as the one I have now?

[Marmalade_dude]

I had a bunch of spare computer parts that are lying around so I decided to build a new computer to compliment my current PC.

My current PC is

Intel Core i7 2700K
EVGA GTX 970 SC GPU
16 GB Kingston hyperX memory
240 gb Intel 730 SSD + 2 TB HDD
Gigabyte z77m-d3h-mvp motherboard
Zalman Z9 plus chassis

The PC I will be building when the parts arrive is:
AMD FX-6300 CPU (6 core CPU)
ASUS HD Radeon 7850 GPU
6 Gb DDR3 memory
1 TB HDD 7200 RPM (may upgrade to SSD)
GIGABYTE 78LMT-USB3 AMD760G motherboard
Fractal Design Node 804 chassis

Will my new PC match the PC I currently have or come close to it?

Not to be a jerk about this, but is this a joke? Did you accidentally swap the builds around? You're going to replace and i7 for a 6300? That's a horrible idea.

He's not replacing it but the amd build is quite a bit lower performance. More than 50% if you're talking gaming.

Oh. Ok. I was about to say.
