yeah looks good. only thing I would change is the PSU, get a cx550 instead of the cv650

well everything is compatible as for "is it good for gaming" depends on a budget I would go with a ryzen build but that's just my opinion, you would save some money for basically the same performance. 

What are your temperatures during idle and load? There’s a possibility that your heatsink got loose when you were taking it apart.

Then I assume it has an HQ i5 or i7 - go into your power plan settings and set maximum CPU performance state to 99% - that'll disable Turbo boost entirely so you'll have ~2.8GHz but at least it should mitigate Asus' terrible design. Basically, this thing needs cooling on high end parts

Highly unlikely. Usually bios updates fix power throttling problem. 
Check vram usage again. Try cleaning the laptop. Dust it off etc. 

You can't fix a shit design. From what I remember correctly about the XPS models, Prochoot throttling is the result of the CPU power delivery hitting 125*C and reducing CPU performance so as to not melt the power delivery on the board. It's what happens when the board design is bad and the VRMs are not cooled.

Update the bios if one is available. 
And with a 1050 ( assuming it's a 2 gig model ) you'll 90% of times end up running out of vram and page filing. 
Check vram usage. 

Sounds like the power delivery is overheating.

No problem, also keep the undervolt, it'll also help a bit. Not by much but it's aomwthing

Repaste with TG Kryonaut and clean the laptop

It means the power target of 45W is not enough for the CPU to sustain clockspeeds. Undervolting won't help as that's only a very minor and small improvement to a shit storm of a situation. The 7700HQ needs about 70W to run full tilt.

That's normal, the 7700HQ is power starved and no amount of undercoating can fix that. Assuming you're getting at least 2.8GHz clocks, I'd just leave it alone

Part way down this page there is instructions https://sff.life/how-to-undervolt-gpu/

Can you monitor CPU and GPU clocks and see if they dip when the FPS drops? You might be thermal throttling.

You can download HWiNFO and run it in the background, when you throttle see if it mentions anything about power/thermal throttling in one its statistics.
 

That's your CPU, does the GPU have any throttling stats?
 
EDIT: Maybe your CPU is throttling? Are you sure it stays at 3.4GHz?

Well if your CPU and GPU temps are in check the next most common thing to cause throttling is the VRM which usually doesn’t have sensors on laptops. You can try undervolting your CPU and GPU or disabling CPU turbo boost.
 
In the Dell XPS community people place thermal pads between the VRM and bottom of the chassis to dissipate heat (it’s metal), or use tiny finned heat spreaders. You could try the same.

Oh, you never mentioned that you said 75-85c. 96c is quite high, try disabling turbo boost with Intel XTU when you game and see how that goes.

It’s the culmination of heat generated when both the CPU and GPU are working that’d cause the CPU to get so hot. They’re both in a small confined space and probably even share the same heat pipe and heat sink.
 
You could try undervolt the GPU as well to something like 0.9v, I did that on my XPS and barely lost any performance because the GPU’s usually have more voltage than they need for the default clocks.
 
Failing that you would have to try repasting with a good thermal paste or liquid metal. Unfortunately these types of laptops aren’t really designed for running heavy mixed usage workloads like video games, my Dell XPS has the exact same problems.

Hello. I've had an Asus laptop (Asus VivoBook Pro 15 N580VD, I'll put the system specs below) since october 2018 and in the last two months or so I've noticed regular and sudden FPS drops in any game I play. While playing Overwatch on high settings and full hd resolution I noticed the following things:
sudden drops from 60fps to 20-30fps GPU temperature constant at 79 celsius , usage at 99% CPU temperature fluctuates regularly between 75-85 celsius and usage at 20-25% Battery settings are set to  "High performance" and graphic card settings to adaptive. I've searched all around the internet and couldn't find a fix or at least the cause of my problem. Could anyone help me? Thanks in advance.
