My motherboard’s power LED is too much.

A 5600 is $250 less than a 5800x3d, and is 65 watts instead of 100. You’ll not come anywhere near justifying a $350 processor unless you’re spending $1000 on the video card as well.

Get yourself a used 5600 for under $100 since everyone is upgrading to a 5800x3d. Then buy yourself whatever GPU you’re comfortable getting with your remaining budget. 6700, 7700, and 7800 are all good, with the 7700 probably being the most future proof per dollar, and 6700 being the most FPS per dollar. The 7800 is in a weird spot. I think it’s probably just there to convince people to get the 7900.

And don’t forget to update the bios before putting the new CPU in :)

Your PSU should be fine. It is rated at up to it’s listed draw. If you wanna be safe, aim for 10% lower. I have a 7900xt + 5800x3d with 2 NVME drives and an AIO. With a kill-a-watt in the wall while gaming, I measure 430 watts going to the power strip for the PC plus 2 monitors (which pull 50 on their own with the tower off). Online power calculators are extra conservative. Your PSU could run my rig.

I also have a good Freesync monitor, and I quite honestly can’t tell the difference between 90fps and 144fps. If you’re getting 80+FPS consistently, let Freesync take care of the rest and don’t worry about it.

If you’re moderately comfortable with the command line, Arch is amazing. I find it considerably easier to find software I want to install, and find answers to problems I have.

I would say that if you’re not interested in learning when something goes wrong, so you’re not really interested in anything other than i don't care I just want it to work then it’s not the distro for you.

The rolling release style is really great and Arch is rock solid, so if you are looking for something a little more user friendly, Endeavor is worth a try as it is Arch based but focused on an easier to use system.

I installed Arch for the first time in March of last year for my primary gaming PC. Previously my gaming PCs were windows but I keep a separate file server and HTPC each running Ubuntu. I’m in the process of switching both of them over to Arch now because I just consider package management and updates so much easier.

NASA says the universe is flat.

It’s impossible to measure precisely enough to know for sure that it is completely flat, or even saddle shaped (both being infinite in size). The generally accepted understanding by cosmologists is that it is infinite. But just due to the nature of measurement and tools we can’t completely rule out a finite universe. However we do know based on the measurements that it is really really… really really really big if it’s not infinite.

The expansion of the universe is measured at 70km per second per megaparsec (~3 million light years).

So if you take 2 things that started say ~3 billion light years apart (which would be ~1000x a megaparsec), that means every single second the universe has existed those 2 points have gotten 70,000km further apart. And now that they’re further apart, they separate even faster the next second.

For reference:

  • 31.5 million seconds in a year. ( 3.15 x 10^7 )
  • universe is 13.8 billion years old ( 1.38 x 10^10 )

So we talking about this 70,000km getting added between the 2 points ~4 x 10^17 times.

Then you gotta bring calculus into it to factor in the changing distance over time.

It … adds up. Which is why you’ll see the estimates for the observable universe’s radius being ~46.5 billion light years (93 billion light year diameter), even though the universe had only existed for ~14 billion years.

The issue with running a PSU exactly at, or very close to, the sustained draw of your system is that it won’t be able to withstand sudden GPU/CPU spikes, that can go way beyond what the PSU is rated for, am I wrong?

The TPD of the components is their max rated draw. They will not exceed that draw. Any spikes under normal operation (aka gaming) are spikes up to that max rated number, not over. If you calculate your component’s max power draw correctly you will never exceed your PSU’s max draw.

At max load a 550W 80+ gold PSU (the one I have) will have 89% efficiency and provide 490W

No. A power supply’s posted wattage is what it is rated to output. That is the max draw it will supply to the internal PC components. The efficiency rating is what tells you how much AC wattage from the wall is required to generate that 550 watts of DC power for the PC components.

A 550W PSU with 85% efficiency will require 647 watts of AC power from the wall to provide that 550W of output. A 90% efficient PSU will require 611 watts from the wall to do the same.

Additionally, PSUs function on curves based on draw. Here’s Corsair’s graph from their Choosing a Power supply page: https://res.cloudinary.com/corsair-pwa/image/upload/f_auto,q_auto/v1665096094/akamai/landing/PSU-Family-Page/diagrams/80Plus_Chart.jpg

Corsair (and most other PSU manufacturers) build their PSUs to maximize efficiency around the 50% load mark, which for a 550W PSU is 275W. However, pay attention to the Y axis of the chart. A Gold PSU is at 90% efficient at 50% load, but it’s still 87% efficient at 80% load.

NVME and SSD drives pull 5W max. Fans are usually in the 2W range but running full speed are in the ~5W range.

Figure out your load requirements and know, don’t guess.


A 5800x3d means you’ll need a bigger PSU, but if you get a bigger PSU, you won’t have enough to get a better GPU, so you won’t need the 5800x3d. If you’re really really insistent on getting something better than the 5600, wait for the 5600x3d. It should be ~$100 cheaper than the 5800x3d which will cover the cost of the PSU and is still a 105w TPD chip. The 5800 is overkill if you don’t have the video card and components needed for it, and 4k gaming is actually slightly less intensive on CPUs compared to 1440p.


The short version of every question about upgrading is that the CPU isn’t going to be what gets you to 120FPS. The GPU is. $100 extra dollars in the CPU is going to give you a couple more FPS. $100 more into the GPU is going to give you 10-20 more FPS.

Personal anecdote: I have a 5800x3d. The performance change when I upgraded from a 5600 was single digit FPS at best for the games I play. It was measurably different, but not perceptibly different. I’d have better performance putting that same money into a better GPU


Which country are you in? Finding a used 5600 should be really easy and cheap.

Oh wow thanks. You learn something new every day! I’m definitely an “armchair physicist”, and still find it hard to think about things in a nonstacically geometric way.

Sounds like the Hubble Constant ain’t so constant :)
