I ran an FX 8350 at 5ghz, and it bottlenecked my SLI GTX 580's. With perfect scaling, they were about equal to a single R9 280. That being said, even an RX 470 would bottleneck pretty hard, but its better than no card at all. I would say get whatever GPU you want, because the performance will be the same with a 470 as it would with a 2080 ti on that CPU. Just be ready to upgrade that poor fx because the gaming experience is very choppy on ANY of those chips.

As long as it doesnt stay at that voltage for any extended duration, like you said, then it wont hurt it. Thats especially true since your temps are wonderful. To give some credit to that statement, my 4790k at 4.7ghz is set to 1.35v in the bios, but during stress tests its more like 1.365v. If I let a torture test run for a few minutes it will spike up to a max of 1.41v, but never for more than a split second, which is the DANGER ZONE for these old haswell chips. It's been on these settings for almost 2 years now, still does the exact same as the day I got it.

Aside from adding another fan to the radiator, theres nothing you can do to make it any cooler. You could get a bigger aio but like you said, you dont have room for it.

Single 120mm/140mm radiator AIO's are just not good. A half decent air cooler will perform the same/better at the same/lower price. I wouldn't recommend any AIO with a radiator smaller than 240mm.

Yeah the 7700k single core 4ghz = 8700k/9700k single core 4ghz. There is VERY little upgrade to be had, only in a handful of games today would it help to have more cores/threads.

Yes. I run both a 144hz monitor and a 60hz smart TV and it works perfectly.

If you read closely theres an RX 570 in the PCPP build he linked. lmao

Those temperatures are bad. It's probably been thermal throttling the whole time, but it simply has gotten worse with age due to dust/old thermal paste etc. You should look into how to open up the laptop, clean her out with a can of air, and repaste the CPU. It would be well worth your time.

Well its clearly throttling to about 1ghz during that stress test as well. I can say its probably overheating.

Aside from turning up the GPU fan, there's nothing that can be done. If it's any consolation, my old FX 8350 / GTX 580 SLI rig was an 800w monster, both 580s and the CPU were max OC'd. The 580's had a much louder blower cooler on them than your 2070 and the top card would touch 89-90*C during the summer months. It was fine, just loud and alarmingly hot. Last I heard both 580's run fine to this day. It doesn't matter that you're at 75c lol dont worry

I will inform you of this as I've tried my best to stay in tune with PC components and stuff since 2012-2013. There won't be anything faster than a 2080 ti (except the Titan RTX which you mentioned) that will come out. RTX is new stuff and there won't be any follow up or refresh to make it any faster. That being said, SLI is optimal in 4k and I'm pretty hard pressed to believe a 9900k bottlenecked anything. If you built a PC with a single 2080 ti and a 9900k, the experience in 4k would be amazing. The Titan RTX would be a LITTLE bit more amazing I guess with a few more fps than a 2080 ti, but the price/performance of that is horrible. I can't say get SLI either because 2 years ago I was running SLI GTX 580's/570's/650tiB's and all of them had different amounts of scaling, none of which were consistently more than 70% on each card. Meaning at most, I had 140% the performance of a single card. It's a decent improvement when it works, but when it doesn't work it often lowers fps or introduces weird issues. About half my steam library was SLI enabled, and the other half not because it made it worse. I don't think its worth twice the power draw and heat output for mostly the same experience 98% of the time. So yeah 9900k/2080ti is best idea for tldr

Uhh thats probably a bottleneck. Hear me out, on my 4790k OC'd to 4.7Ghz I can drop below 60fps in a few areas of the city and its entirely the CPU's fault. My Fury drops to like 80% usage and the i7 is at 95% usage maxed out on 4 cores and almost on the other 4 threads. An r5 1400 isn't quite as good as my i7, more like a 2600k at the same clocks. I'm willing to bet its a bottleneck for his 580. Those quad core ryzen 1000 chips arent anything special sadly.

To be 100% fair, I lost brain cells seeing Linus attempt to glue a chip together. But, ITS LINUS. THE HELL DID YOU EXPECT? SAME MAN WHO SHOT A PSU FROM A SLINGSHOT TO SEE IF THE PACKAGING WAS GOOD? @LinusTech Thank you dad for your wholesome content I meant no disrespect.

Yeah it will be fine until you upgrade in that case. My i7 4790k isn't massively better than your i5 and it holds up well.

It may bottleneck a little bit in the newest of new games. It's a 4c/4t chip btw, no hyperthreading on i5's. 99% of the time it will probably be just fine tho
