New PC

[Nexi]

Hello. I started looking into buying new PC and I don't know what I'm doing. So I would appreciate if someone could help me choose what to buy. I'm not in a hurry or anything so I can wait for stuff to be available.

I would prefer to not go over 2300€. From my old PC I probably can only keep my SSD. I was thinking about going with 3080 for the graphic card and meaby ryzen 9 5900x but I'm not sure how good amd stuff is. I have 4x4 2400hz RAM which is proabably too weak for what i'm trying to buy.

My SSD:

Samsung 970 EVO Plus 500GB M.2 2280 PCI-E x4 Gen3 NVMe (MZ-V7S500BW)

Samsung 860 EVO 250GB

I'm also looking to buy good 1440p 144+Hz monitor if someone have good recommendation.

I'm probably gonna buy this from here: https://www.morele.net/

I have an LG 27GL850, it's a freesync and gsync compatible IPS and runs 144Hz, (48 to 144 variable). I really like it.

I think that will be the best monitor for that price thanks.

I did some poor research and picked some parts that seem like would work together but probably won't.

Asus TUF GeForce RTX 3080 Gaming 10GB GDDR6X (TUF-RTX3080-10G-GAMING) - no clue about the difference other than apperance between all of them tbh

AMD Ryzen 9 5900X, 3.7GHz, 64 MB, BOX (100-100000061WOF) - intel seems worse atm?

MSI MPG X570 GAMING PLUS - no idea what to pick for motherboard so I just took bestsellling one that looks right

I kinda have no clue what RAM I need. I have read that 3600Hz is good for this CPU so I picked this two that I don't really know difference between:

G.Skill Ripjaws V, DDR4, 32 GB, 3600MHz, CL16 (F4-3600C16D-32GVKC) v Pamięć G.Skill Trident Z Neo, DDR4, 32 GB, 3600MHz, CL16 (F4-3600C16D-32GTZNC) - never heard about that company but its best selling one with good opinions so idk

SilentiumPC Supremo FM2 Gold 750W (SPC169) - idk how much power I need

I have no idea what case and cooling I need for all of this.

That looks great Nexi - I have never heard of that power supply, but all the rest looks great to me - I would check the exact serial for the RAM and check the QVL list for that specific motherboard to make sure they work well together.

That will be a beastly PC, that is for sure!

For gaming - today - The 5600x might be a better buy, but I am gonna get the 5900x as well, so who am I to advice in the saving money department 😛

Yeah just preorder teh 5900x. It will last you the next 8 years easily. 

The AMD will benefit ALOT from having fast memory, 3600 is the minimum, if you can get faster RAM try to do so.

 

3080 is a beast. 

[Nexi]

I might need 850W PSU I don't really know how to tell how many W I need.

I would get faster RAM but above 3600 it almost doubles in price.

Also do I need something like CPU be quiet! Dark Rock 4 Pro (BK022) for CPU cooling?

You can get faster ram at same frequency dropping the CL number, and AMD chips are supposed to really benefit from the lower timings. For example, 3600 CL15 could beat 4000 CL17. There is a formula to work that out somehow, but lower latency is better for the RYZEN architecture 

850w better option, you want the headroom and some 3080 run over 400w.

3600mhz at cl16 is pretty much the sweet spot though when it comes to price/performance to be honest.

The RAM has to run in a 1:1 ratio with the infinity fabric for maximum performance, and the default speed of the infinity fabric is 1800mhz (3600mhz memory is dual blabla, so it's actually 1800mhz, so perfect fit).

Most Ryzen 5xxx can, on a solid motherboard, run the infinity fabric at 1900mhz, but that means a hassle overclocking, and you'd need QVL memory that can run at 3800mhz for sure, which means dipping a lot deeper into the wallet for ~5% performance increase, if even that.

AMD has claimed new BIOS will help overclocking the infinity fabric to 2000mhz, but that is not yet tested or proven. Almost no chips can run at 2k at the moment.

Running, for example 3800mhz memory, while not overclocking the infinity fabric speed, is actually significantly slower, than running 3600mhz memory at 1:1 ratio. It's back to the old days of FSB overclocking hehe.

So, to conclude, 3600mhz is what you want. CL16 is good for that speed, anything faster than that will start costing you an arm and a leg.

 

I have put in order for Motherboard, 5900x and some RAM, and I went with 3600mhz CL16

Thanks for help guys, I will probably end up ordering this. I just need to convince myself to spend that much money.

AMD Ryzen 9 5900X, 3.7GHz, 64 MB, BOX (100-100000061WOF)

Asus TUF GeForce RTX 3080 Gaming 10GB GDDR6X (TUF-RTX3080-10G-GAMING)

Asus TUF GAMING X570-PLUS

G.Skill Ripjaws V, DDR4, 32 GB, 3600MHz, CL16 (F4-3600C16D-32GVKC)

Corsair RM 850i 850W (CP-9020083-EU)

be quiet! Pure Base 500DX (BGW37)

be quiet! Dark Rock 4 Pro (BK022)

I will probably order monitor after they send me PC because I can't really use 1440p with my current setup.
