I'm going with the assumption that you're not going to overclock your RAM and you're going to leave your CPU at stock.

Huh? Seasonic have made trash what do you mean lmao. Going by brand is dumb they're not perfect lol. Literally every brand has at some point sold subpar/bad PSUs.

oh no no no.... They don't even make their RAM????? They get ICs from Hynix, Samsung, Micron or other manufacturers. Seeing has Samsung BDie is pre crazy to OC as well like where did you draw that conclusion mate? Also, wtf is ram for "gaming" ???????

I understand this, but the brands I mentioned are very reliable brands, but Samsung is not a very reputable brand when it comes to ram. I would personally go with the brands I listed. 

They are okay but go with Corsair, HyperX, G.Skill, or Kingston.

Yes but the filters are crap

you mean rtx 2060? 5700XT is much better

Innefficiencies is not what would impact the lifespan of the part.....
Actually, efficiency only refferences the ammount of waste heat used...... Nothing else......
 
Efficiency doesnt reference what parts are used....... It can give a pointer to what topology is used, but also not really. 
 
While not wrong, depending on the region, terrible advice as some units cost a lot, while other very little. 
There are platinum rated group regs....... Iirc. 

It isn't too hot. You have a 12core CPU? Do you magically expect it to run at 20c idle and 50c under extreme load?
 
The max temp is 95c, which you are 5c under, and the CPU will auto-downclock to prevent damage.

TestMem5/Memtest - RAM
Time Spy and Firestrike - GPUs

im on 4.45Ghz on my 3600 at 1.268 volts. not luck. its just that the early batches of silicon in the 3600 were bad compared to the 2020 batches. also there is a reddit post about people's cpus degrading.

1.35v is not safe for zen 2 in any strech.

Do you have them in slots 1/3? If so put them on slots 2/4

You sent a reddit post about idle voltages " It is perfectly okay if your CPU is periodically using 1.4-1.5V to achieve boost frequencies, and you should see dips into sub-1.0V as the CPU goes into idle.". People have literally reported their CPUs either no longer being able to run their OC stable or STOCK stable after a few weeks - months. The lowest voltage I could find that degraded was 1.285 or whatever the increment is.

Considering that we have ZEN 2 CPUs degrading at voltages higher than 1.28 I'd suggest chilling on the voltage.

Pulled this off of the ryzen 3rd gen overclocking video. Anthony shows safe and redline voltages and other little tweaks in the BIOS

OC the ram to 3600 CL14/16 | 3800 CL14/16. It'll depend on your luck as to how good they'll overclock but CL16 is definitely achievable with both 3600Mhz and 3800Mhz.

these 2 are sadly not compatible. 
 
edit: also
this isnt really a great choice for what you are intending it to do. its singlerail, which at these high wattages isnt ideal. 
 
edit2:
thats not really a great SSD for the money while it also doesnt really offer anything that cheaper drives can also offer. 

I love how if one of the busiest post's of recent is about leaving console's 😂

and don't get me wrong I know going all ROG isn't the best option but sadly I'm a very aesthetic focused idiot

But you have the cash to spend it all on a ROG look?
 
Like all we are saying is that stuff is comming in Q4. Since you should allready wait untill you can buy it all at once, why not wait for new hardware?
 
Also if you have to go with an ROG look, at the very least reconsider some of the components, like PSU or Cooler to other options. 

https://pcpartpicker.com/user/John0531/saved/4qz4dC this is what i would do for the tower, and then i added some peripherals. also, you need to know intel bad, amd good for cpus, not i3 vs i9. also, i could make you a more practical build

That's 5000 quid. OP said 3000.

That's 5000 quid. OP said 3000.

If you're only interested in playing COD, wait for the new one to come out before you build. New hardware will be coming out around that time. And there would be no point spending £50 on Modern Warfare when a new one comes out in like 3 months or so.
