Wondering if a Nvidia GTX 1070 is compatible with my computer.

[rbarnes]

I am new to PC gaming and do not know a ton about them, and I wanted to know if my PC is able to use a Nvidia GTX 1070.

My PC:https://www.bestbuy.com/site/cyberpowerpc-gamer-ultra-desktop-amd-fx-6300-8gb-memory-amd-radeon-rx-560-1tb-hard-drive-black/6072200.p?skuId=6072200


I just bought a cheap pre-built one to start off with because i was so eager to make the switch, with the intention of gradually upgrading over time. I will be getting a 750W PSU tomorrow.

Any help is apprciated!

Not worth pairing a 1070 with a FX6300.

Save for a newer platform.

Only addressing the PSU/power consumption issue (not the potential CPU bottle necking):

That should be fine upgrade. The existing PSU, if it can handle a RX 560, will definitely be able to handle a more efficient GTX 1070. The PSU is a quality unit from EVGA, so that's good. Of course a PSU upgrade will allow for more confidence if you are overclocking. The existing 450 watts is sort of the bare minimum.

Wow, I wish you'd asked BEFORE you bought the pre-built since we could have made one on pcpartpicker (then you would build it).

Now as for the FX-6300 bottleneck as suggested by SR-71....

The amount of CPU bottleneck depends on:
a) game
b) game settings (including resolution)

So it varies a lot but yes many games will see a big bottleneck thus it may be better to look at say a GTX1060 6GB.

If I had to GUESS based on many benchmarks I've seen on CPU scaling I'd say you'd on average use about 80% of the GTX1070, with some games being closer to 100% (no cpu bottleneck) and some games being even under 60% (severe CPU bottleneck).

So there WILL be situations a GTX1070 performs better than a GTX1060 but I'm not sure it's enough to justify the cost difference.

*My advice is a dual-fan GTX1060 6GB card similar to this:

PSU may not be needed... I'll run a calculation (if not may still need a 6/8-pin PCIe adapter).

1) Power without graphics card: https://www.anandtech.com/show/6396/the-vishera-review-amd-fx8350-fx8320-fx6300-and-fx4300-tested/6

about 150W

2) GTX1060 peak power
about 150W

So probably in GAMING you wouldn't go over 300W... you can use more than 150W on the CPU at 100% usage but then likely would not also be using the graphics card.

So let's call 300W for gaming and 350W worst-case.

*450W is probably fine. still check the specs to see what it delivers and if it's a good PSU (overvoltage and overcurrent).

If any doubts at all get a better PSU... I can tell you I use less than 375W (probably about 325W) with this:

i7-3770K at 4.4GHz
GTX1080
16GB DDR3
etc

I know that because I have ECO MODE on my 750W EVGA G2 but the fan never spins up (except on boot). Thus I've never hit over 375W with this setup... so I think 300W is going to be your absolute max gaming.

ADAPTERS:
If you need say a 6-pin PCIe there are MOLEX or SATA adapters. ask if you might get one.
