how reliable are amazon second hand deals? im looking a 6600xt almost 150 bucks cheaper than a new one

Go for it. I've gotten some fantastic deals even buying "used - acceptable" condition items from their warehouse. About half the time I have doubts the item was ever even opened to begin with. Avoid third party sellers however since that could be a potential headache if you end up needing to return something.

Can someone give me a balanced take on AMD's gpus? They look overpriced and underpowered. They dont have things like nvbroadcast. What are AMD gpus good for?

They're good for playing video games and are usually a bit better on price vs performance compared to NVIDIA cards.
 
The 7900 XT and XTX do seem to have issues in some games/software due to the new chiplet design. Time will tell if this can be fixed by drivers or they're able to tweak the design for the release of the mainstream cards. I'd still pick 7900 XTX over the 4080 if I had to, but both are overpriced.

I decided to "upgrade" my GPU to an RX 580. Should be as easy as swapping it in, right?
  1. 500w power supply shits itself 2 hours into testing.
  2. Replace PSU, system is stable, but temps are getting too high.
  3. I realize the card is too big for the case and is effectively blocking off airflow.
  4. No coolers to throw on it so I dig out this fucking huge Corsair case and move all the hardware over.
  5. Temps are great, start gaming.
  6. My main monitor begins to flicker on and off inexplicably.
  7. Remount GPU, triple check all connections. Nothing helps.
  8. Start digging through shit online, realize the only display blanking is connected via DP.
  9. Get into the autism of "certified" DP connectors and realize I only have generic shit.
  10. Get pissed off.
  11. Open up menu on the monitor, toggle off "DP 1.2", problem goes away.
I figured this would be a good half-step towards a new PC in a year or so, but after all this I'm just going to run this thing into the ground like I've done with every other PC I've had. I'm NOT going through this vague troubleshooting shit again because I added ONE new part. Can't imagine all the stuff you have to do with a 100% new build.

So it appears Ryzen CPUs are now overheating and failing (mainly the R5 3600 but others are affected like the R3 3300X). One of the theories is that many motherboards by default are sending more voltage than the CPU can handle and while undervolting and switching coolers seems to help, it's a safe bet many people experiencing this will not know what is going on and why.

Fellas I wanna swap my old video card for something new cause it is really getting old and not handling some new stuff I wanna play. Motherboard is a MSI X470 and the PSU is a Corsair CX650. I am looking to a AMD RX 6650 XT due to finding one in a decent price and the fact it is AMD means better driver support for my Linux. However it says the minimum PSU it requires is a 650 watt one, does this mean I should be weary of actually getting it unless I can also update the PSU? I would rather not buy it and end up causing some magic smoke to materialize.

Also open to have the choice of GPU criticized if you guys think it is a bad choice.

The beginnings of the enthusiast market! Going beyond that in the early days was crazy. Water cooling? Go to the store that sells aquarium equipment, buy pumps and tubes. Go to the guy working with AutoCad then go to the guy with the CNC. At that point you were 50% there, zero online guides on how to do it. Good times.

I think that for home users (not professional overclockers) this reached its peak with the toothpaste TIM on the 4-6 core CPUs from Intel and the emergence of delidding and liquid metal. That was satisfying stuff with great results.
In the more distant past, CPUs like some low end Core 2 Duos and Celerons before that overclocked like mad, Intel used to sell CPUs at 1.8GHz that you could run relatively easily at 3GHz. Had a E7200 2.53GHz C2D, and I think I was running it at 3.8 or something, and it could go even higher but my cooler was meh.
I guess that makes the Coffee Lake 8th series the last interesting TIM CPUs to delid and fool around with easily, without needing to scrape off the iridium TIM like today, for minimal gains.

That GPU seems to use about 150W in Cyberpunk with RT at max usage. Unless you have a 300W+ CPU that PSU is more than enough, even as Bronze one.
You should be able to run even a 250-280W GPU like the 4070Ti off it, although that's starting to push it a bit.

Still astonished me that I can just plug a new GPU into my computer and not fuck with drivers for the next ten days

Same, but with motherboards. Third party AMD motherboards during the Athlon era could be a real pain in the ass. First gen SATA chipsets could be hit or miss, using on board ethernet might blue screen the computer randomly, on board sound might be crackling because of interference etc. Then there was WiFi and laptops, it was such a relief when Intel rolled out Centrino and things Just Worked. And the stationary sheet metal cases with no easy access that were also sharp as fuck... Lian-Li cases felt like an investment in personal health and safety.

What I liked about that time was that the PSU requirements were "do you have one?".

Outside of some rare circumstances, nobody should bother anymore, or they should try underclocking instead.

Raspberry Pi 4? Do overclock to go from awful to slightly less awful. Surprise unlocked i3-12100 may be faster than the relocked i3-13100, RIP in power/performance. I need to check some of the 13100 reviews to see if they have the 12100 stomping it.

Suggested PSU on techpowerup site is 450 watt: https://www.techpowerup.com/gpu-specs/radeon-rx-6650-xt.c3898

Even if you have a 125 watt CPU, (125 + 176 gpu + 50 misc) * 1.2 = 420, so 450 is fine.

Ah so I must have misread the specs. The GPU only needs about 180 watts of power and the 650 is a general reccomendation taking in account the entire setup not a minimum requirement. My CPU is a Ryzen 7 2700x with a 105 power drain so it should be perfectly fine then. Though I might wanna look into better ventilation.

Speaking of liquid cooling NaK cooled enthusiast PCs when?
