Ryzen 9 5900x any good for gaming?
i7 6700k owner here. I dont want to bottleneck my RTX 3080 anymore. Cheerio.
Amazon sells it for £ 458. Its good, no?

5800X isn't hotter, it draws less power. The whole Zen3 stack runs pretty hot, but Ryzen 9 runs hotter and needs a good liquid cooling solution.
Oh man. I have no idea then. How hotter ia 5900x and one user conformed that corsaie 115i platinum will be sufficient.

A good air cooler too is enough as a Scythe Fuma 2 (I have that cpu with it).
A decent 280mm or large tower air cooler are good enough, but the thing is, boost clocks scale better with lower temperature, so the cooler you can keep your CPU, the better the clocks your CPU can sustain, since the algorithm is heavily based on temperature, as higher temperature brings greater risk with electromigration which is where problems occur when using more voltage as it can lead to the gradual degradation of the silicon. It's why since AMD started using TSMC's 7nm process that they had to employ the use of the Silicon Fitness in order to prevent their CPUs from burning themselves out by always trying to run up to their maximum boost frequency on more than a single core.

I got extra life from my i7 6700k by overcklocking it. Is Ryzen 9 5900x easy to overcklock? Can you squeeze more out of it when need arises?
I wouldn't advise manual overclocking for Ryzen because changing the CPU multiplier disables the Silicon Fitness, which is there to prevent the chip from destroying the silicon by using too much voltage based on temperature and current. If you run a manual OC on 7nm (or lower) Ryzen, you absolutely need some pretty heavy vdroop to compensate for the risk, it's easier and usually best to just let Precision Boost Overdrive do its thing, and use the Curve Optimiser to adjust the curve to get better results.

The more cores has and the more power the CPU needs, the lower the safe voltages are going to be when the system is using more of those cores and threads; most 3600s and 5600Xs can handle 1.3 volts all day, while the 3950X and 5950X rarely can safely handle more than 1.2v in an all-core load because there's significantly more current draw and temperature resulting from it. For manual overclocking, the lower end SKUs are actually better in that regard because of the lower core count results in lower power demands and less heat.

I would never suggest taking that kind of risk with an expensive processor like a 5900X or 5950X. It's not worth it, the headroom is so minimal that it's safer and better to just use PBO.

Their TDP isn't that absurd. I remember the AMD FX-9590 sitting at 200 Watts stock while a 5900X uses as much as a highly overclocked 7700K at around 130 Watts.
It needs good but not extreme cooling.

It can use up to around 180W easily with PBO enabled in some loads. At stock it can go up to 142W as per the 105W TDP spec. (Default PPT at stock for 105W is 142W)

It's not about how much power it's using, rather how efficient it is with that power. The FX-9590 is just a waste of 200W because of how bad of a processor it is, while the 5900X is efficient use of ~200W.

Merely because frequency scaling is better with lower temperatures, it's a good idea to have good cooling. You're not necessarily getting the most out of the CPU if you're using a 212 EVO, a 240mm AIO, or similar. More like ~90% of it.

Guys, why intel i9 10900 scored more in Red Dead Redemption 2 than Ryzen CPUs?

Why are you surprised?
Intel and Ryzen has equal performance. In some games intel wins, and in some games Ryzen.
An overclocked i9 10900k usually surpasses the Ryzen in many cases.
Oh no, I just wanted to future proof a little bit. 4-5 years. I did not have enough dough to buy 5950x but 5900x was within reach. I hope it will last now.
Ok guys I pulled the trigger on R9 5900X. It will come soon. It needs to last for at least 4-5 years. Please make it happen.

What I can say is... Enjoy your little beast man :Demon_X3:

I'll hope that you don't need to maje it last 4-5 years, that will mean you are either making more money or you've learned to save and budget better :)

With thst said, it should be good unless something drastically changes, which is unlikely, even if they graphene chips commercially viable tomorrow that were (a hyperthetical) 10x faster, it would still take several years for them to even begin to be utilised so you would likely still have 3-5 years before anything would fail to run anything.

get a good board for it
one with 10+ choke coils (small bricks) around the cpu socket and heatsinks near them
I would have definitely got the 5600x over the 5900x for gaming, but that's just me. The 5600x is about the same performance for much cheaper.
A single chiplet design vs a dual chiplet design will be better for fps and latency. This is why Intel CPU often performs better because of its monolithic design.
The 5900x is definitely nice. You could've saved though and had prety much the same exact PC experience.

I did go for MSI X570 MAG Tomahawk. I have heard good things about this board.

The thing about current gen Ryzen is that, they run hot no matter what you use for cooling. A 280 CLC is enough for 5900X, just don't be too worry about temps, just don't expact to see temps in the 60s or even low 70s under full load.

We don't have any control over that.

That being said, plenty of midrange CPU's over the last decade have been serviceable for years much longer than five years. I don't think current high end CPU's have anything to worry about.

not a bad choice
but be aware the sb fan (near the io headers and sata ports) will fail in about a year
if you get weird issues like audio cutouts, usb devices not reporting and/or sata drives not working that will most likely be the problem

O wow, thanks for the tip. Is this the case for majority of these boards? Obviously RMA'ing a board is a pain. I am staring to think that this upgrade was a terrible idea.....
