last week i purchased a new gpu hoping it will make a difference that gpu is rx 580 8gb (Gigabyte) but i see little to no improvement my cpu is amd a10 7860k do you think my cpu is bottlenecking my gpu ?
other specs
8gb ram ddr3
500gb Hard drive storage
asus a68hm-k motherboard
500 watts psu
stock amd cooler

If its bottlenecking what should i do ?
(new to pc) THANKS!!!!

Yes that A10 is going to bottleneck with an RX 580. You need an i5 or ryzen cpu to take full advantage of it, although even a cheap g4560 would be an improvement for you.

What game are you playing? And what was your old GPU?

What FPS are getting in the specific game you're playing? (Use Fraps if you don't have an in-game FPS display option).
Have you checked your temps while you're gaming? (Use HW-Monitor or similar, focusing specifically on CPU temps).

We are increasingly seeing CPU heavy titles, and the RX580 will likely be held back by your CPU in those games. But there are still plenty of games which ask much less of the CPU and will allow the RX580 to stretch its legs. It's possible - and worth checking to make sure - there's no other issue with the system.

There's only one way to be sure, and that's for you to find yourself.

I recommend installing MSI Afterburner and set up the On Screen Display to show CPU Usage, GPU usage and frame rate.
Go into the game your having issues with, and toggle on the onscreen display. If your CPU is near 100% it's bottlenecking.

Another way to find out is to run the game with issues on, and turn down the resolution to 720p. This will relieve the load on the GPU and (hopefully) place the boundary on the CPU. The frame rate you experience there will be the CPUs boundaries.

However, if you are receiving FPS at or higher than your FPS desire, or above your monitor's refresh rate, bottlenecking isn't a worry.

Id it is a problem though, you can try overclocking a little bit, and see if there are any in game options like View Distance, possibly shadow quality, and physics and turn them down to relieve the workload put on the CPU.

There isnt a real worthwhile upgrade using that platform.

In the meantime, you can turn your graphics settings as high as you can while still being CPU bottle necked.

Some great advice there.

The only thing I would reiterate to OP before considering an upgrade is that it really is worth checking CPU temps. I've saved so many people with older rigs unnecessary system upgrades simply by taking some compressed air to their CPU heatsync.

Guys when i benchmark it here are the results
1st application (furmark) 77 fps 1920x1080p msaa off
cpu usage :11%
gpu usage : 100%

2nd application (valley benchmark) 64 fps
cpu usage : 62%
gpu usage : 100%

So no CPU bottleneck in the Valley benchmark (or Furmark, but that's not designed to hit CPUs at all - so as expected).
Different titles will behave differently.

What about the games you're playing at the moment?

CSGO 90-300 fps
overwatach 50-90 fps
rocket league 90-125 fps
dota 2 100-135 fps

the problem is the overwatch at max settings it will get 50-90 fps when its in the lowest settings still the same 50-90 fps

3/4 of those games have no concern of CPU bottlenecking as long as you have a 60hz monitor (most like considering your CPU's age). Overwatch is looking like a CPU bottleneck, although I wouldn't expect 50 FPS not playable? Make sure to read the other posts.

So you're getting great performance in 3 out of 4 titles, and decent -> good performance in one (Overwatch). You only have a 60hz monitor, is that right? So there's really no point in getting over 60fps. Overwatch is the only CPU limited title, and even there you're still pretty close to 60fps. Unless your monitor is faster I think everything is fine. Play at max settings in overwatch and accept some frame dips under 60. Start saving for an upgrade if that's not enough for you.
You could look into OCing which will help a little.
You should also check temps (as I've been advising numbers of times!!)

But I think everything's looking pretty good there.

Well that's all good.

So yeah - CPU bottleneck that's noticeably affecting performance a little bit in one of your current titles. I think that's pretty good all things considered.

Until you have the budget for a CPU + Mobo + Ram upgrade, you should probably see if you can find CPU benchmarks for any new titles before you buy. Then you can make an informed choice about the sort of performance you can expect from the game.
