Will my current a-10 7850k be a bottleneck in a setup with either a 1060, rx 570 or rx 580 in games like gta v, battlefield 4 and 1, csgo etc?

Yes.
The CPU portion of the APU is similar to an FX-4300.

The amount of bottleneck varies on several factors though:

1. game
2. resolution
3. game settings used

It doesn't mean you shouldn't get a GTX1060 6GB card then later upgrade your build though as there are some games that have minimal CPU bottleneck even from an FX-4300 + GTX1060 build.

For example: https://www.techspot.com/review/1128-rise-of-the-tomb-raider-benchmarks/page5.html

There are other games that would gain more than 50% higher FPS but then you'd need to spend a lot of money for the CPU+Motherboard+DDR4 memory etc.

If you have a Freesync monitor or may get one I'd consider an AMD graphics card.

Then make sure the max/min ratio of the monitor is at least 2.5x (i.e. 30Hz to 75Hz).... but not 40Hz to 60Hz.

If Freesync doesn't look likely get NVidia as DX11 driver load (most games now still) use more CPU with the AMD drivers.

I currently have a 1080p 144hz freesync monitor. Though, is it worth getting the rx 570 4gb with lower clock speeds to get freesync over the 1060 3gb in said games?

If I get the 1060 3gb or 470 4gb now, how much of a bottleneck, (approx. In fps) do you think the cpu would be in gta v and battlefield? Please also note that the 7850K is overclocked to 4,1 Ghz

Thanks

I would not buy a RX-570 or similar AMD card now since you're limited in funds. I don't think spending $300 on a 1080p, Freesync monitor then another $200+ on a medium/low end graphics card is ideal.

You should at the very least get the 144Hz monitor first, use VSYNC OFF and see how your experience goes. The FPS/Hz ratio will affect how much screen tearing is obvious (and other factors).

So for example, maybe tweak settings so you get an average of 40FPS or more in GTA 5 and see how your experience is. I discovered that I'd get a major STUTTERING in GTA5 if I used VSYNC but dropped below the target (60FPS for 60Hz monitor) so I forced on Adaptive VSYNC which then turned VSYNC OFF automatically if I dropped below 60FPS.

That doesn't really matter to you in general at 144Hz, though as I said above you may find games where 72FPS (for VSYNC ON) via the half Adaptive VSync option makes sense.

(the reason for the FPS/Hz ratio importance to screen tearing is that with VSYNC ON you send one frame for each screen refresh but that adds latency so it's more SLUGGISH. Especially at lower Hz... now let's say your refresh is 60Hz and you have 180FPS; that means THREE or FOUR different parts of successive frames are joined together during one refresh cycle..

It's like ripping out the top THIRD of a magazine page, then the MIDDLE of the next page, then the BOTTOM of the third page and gluing them together.

However, if the reverse is true and you have the screen updating 144x per second but updated the screen at 48FPS then the screen is updating 3x for every new frame that is created so screen tearing is hard to observe.

*I'm not sure how getting 100FPS+ for a 144Hz monitor will end up looking. Frankly, I've had similarly looking games have minimal screen tear at the same average FPS and some have horrible screen tear which confuses me a bit. I even had about 200FPS in a shooter on a 60Hz monitor and couldn't see obvious screen tearing which also doesn't make sense to me. Weird.)

BOTTLENECK in GTA5 and BF1?

I'd be really GUESSING because often the benchmarks are useless. It varies by map size as well as other factors. In general either the CPU is the bottleneck of the GPU is but in the end I'd just tweak the game settings to hit the FPS you want.

You can search YOUTUBE to find similar setups:

Geforce Experience for some games can apply a profile that aims for 40FPS (AFAIK) based on your hardware so you can see if that makes sense for some games. Otherwise tweak manually for your FPS goal.

I repeat that you should use VSYNC OFF (for 144Hz monitor) as long as screen tearing isn't annoying then just tweak the game settings for the best balance between FPS and visuals.

I probably would wait to upgrade further after this point until you can build a completely new computer in a couple years. (maybe an 8-core ZEN2 CPU or similar Intel).

Thank you!
Though, I'm sorry if there was a misunderstand; I already have the 144hz 1080p freesync monitor.
I was wondering if freesync it with the 570, or should I just get the 1060 3gb since it is faster and generally performs better.

Also, I am trying to get some money to build a new computer. However my current GPU is some old asus r7 250 with 1 gb of vram and I really cannot play the latest games with more than low settings, sometimes I even need to lower the resolution. So I need something that works for now.

Get the GTX570. Definitely.

It's average performance is actually the same, though in CPU-bound titles it will suffer a little due to AMD using more CPU cycles in their pre-DX12/Vulkan drivers (i.e. DX11).

https://www.techpowerup.com/reviews/Sapphire/RX_570_Pulse/30.html

But...

*With FREESYNC enabled you can simply tweak for the average FPS you want. Maybe 40FPS for slower games, 80FPS+ for faster shooters. You don't deal with VSYNC ON/OFF issues (ON you get screen tearing if you can't maintain the target, or added LAG especially at lower FPS)...

... with VSYNC OFF you get SCREEN TEARING.

FREESYNC:
a) NO screen tearing
b) NO added lag
c) no FPS target to be struggling to hit for games you want VSYNC ON (due to bad screen tearing... i.e. trying to maintain 72FPS via Adaptive VSYNC Half Refresh)

Freesync makes this just so much better.

In addition you get 4GB vs 3GB on the GTX1060 3GB version. So that extra 1GB is handy for some games.

Finally, future games will do a bit better on AMD's architecture. In theory at least.

I'm sorry but could you explain what you mean by better experience?

Sure.
Your main choices right now without Freesync are:

VSYNC ON - game stutters, and added lag
VSYNC OFF - screen tearing
(may be minimal due to 144Hz refresh but hard to predict, plus for higher FPS games screen tearing should be more noticeable... the lower the FPS/Hz ratio the better. 40FPS on 144Hz has less tear than 120FPS on 144Hz monitor)

Adaptive VSYNC (Half Refresh) - if screen tearing is bad this is an option too so you can attempt to synch to 72FPS but drop below and it turns off VSYNC to avoid stutter issues (VSYNC ON at 72FPS, but VSYNC OFF below 72FPS)

What? Exactly... it's confusing.

*With FREESYNC the monitor updates the screen only when told too. All the above issues are caused due to the monitor updating at a specific interval (144x per second) which then is hard to match to the GPU output which varies.

So you create a monitor that updates only when told to. Problems solved. No screen tearing because it just draws an entire frame once it gets it. No added LAG due to BUFFERING with VSYNC until the next refresh of the monitor.

**If we assume screen tearing is not obvious then the experience would be the same. Slightly higher FPS on the NVidia card but not enough to really matter (just drop a setting or two to hit the target FPS).

So at best roughly the same experience. Of course many OTHER GAMES work much better with Freesync depending on the FPS used and other factors.
