Need suggestions on how to improve my PC build£

Watercooling always looks nice, but proepr air cooling is better, especially the Noctua coolers, they don't have bling bling.
Watercooling only cools the CPU, but the Voltage Regulator Modules, short VRM's, that provide the power to the CPU, cab get so hot, you cannot touch them without burning your fingers.
Proper airflow directly over the VRMS is important.
The memory controller is integrated in the CPU, it is not on the baord and on a 2600 CPU runs at 2933MHz

Overclocking to 3000, 3200, or 3600, has absolutely no effect on the overall performance of your system, unless the latency timing is lower on the XMP profiles, which it usually isn't.
NZXT case is standing her under my desk, no separate headphone/mic plug and only 1 USB3 port, and one USB C, also the quality is not that great, and when it comes to airflow, it is really bad,
Fractal design Focus G, is available in 5 different colors, and is not expensive, and has great airflow
Memory, I personally used patriot Viper kits, inmeny builds, works blrilliant
Power supplies, go for a true memory manufacturer like Seasonic, and go for 800Watt or above, graphics cards, can have huge peak loads, and EOM brands like Corsair, cut costs, by letting other companies, like Seasonic building OEM PSU's with different specs, go for the Gold certifation or above, the Seasonic Prime have an extremely long lifespan.
For mnotherboard, you can also go for B550 steel Legend (a 2600 wil not work, go for 3 or 5000 series), I don't know if you really need Wifi, if not, skip it, LAN cable is always more reliable, and faster.
Wifi channels contineously change because other Wifi devices, keep selecting different channels
A Wifi card, with remote antenna's is better
And for your OS, go for one NVME (PCIE) M.2, the speed is maybe 10 times higher as your HDD will ever reach
A real SATA3 HDD doesn't exist, only the drive electronics ar SATA3, but mechanically it is impossible to transfer data aqt SATA 3 speed, when you're lucky, you will receive maybe 230 to 240MB/Sec, an M.2 goes above 2000MB/Sec, and doesn't need cables, look for a PCIE (NVME) M.2, Samsung has very good ones.
Your system, will boot faster, and it increases performance dramatically, over a harddisk.
That is what you want in games, it doesn't really matetr if you use 2x 8GB, or 2x 16GB, at least not when gaming, that is more about disk access, and data transfer, and your GPU

Hi Nancy,

I recommend this list: -

1) 5600x US$ 200
= https://www.amazon.com/AMD-Ryzen-5600X-12-Thread-Processor/dp/B08166SLDF/ref=sr_1_1?crid=26F2K35OAABV6&keywords=ryzen+5600x&qid=1660097492&sprefix=ryzen+5600x%2Caps%2C333&sr=8-1

2) B550 chipset motherboard
example 1 = ASRock B550M-HDV = cheapest = US$ 101
=> DIY self add heatsinks to VRM = https://www.amazon.com/ASRock-B550M-HDV-Supports-Processors-Motherboard/dp/B089W26FCB/ref=sr_1_8?keywords=asrock+b550&qid=1660097608&sprefix=asrock+%2Caps%2C415&sr=8-8

example 2 = not cheapest = already have heatsinks on VRM = US$ 139
ASRock B550M Steel Legend
https://www.amazon.com/ASRock-B550M-Supports-Processors-Motherboard/dp/B089W2Q2QC/ref=sr_1_3?content-id=amzn1.sym.0cb3fee0-1a32-4834-9630-18d74b7cf46e%3Aamzn1.sym.0cb3fee0-1a32-4834-9630-18d74b7cf46e&keywords=asrock+b550m&pd_rd_r=f20cd01d-0d8e-457b-bb2a-97f06a63dbf5&pd_rd_w=GhQxs&pd_rd_wg=j3Aup&pf_rd_p=0cb3fee0-1a32-4834-9630-18d74b7cf46e&pf_rd_r=EE7V38CJNJ45WRMGZWVE&qid=1660097797&sr=8-3

item 3 = 5600x comes with Wraith Stealth Cooler - should be just enough, no point going to liquid cooling for this CPU. Only 65 watts Thermal Dissipation (TDP). No need to waste money.

item 4 = your selection is OK

item 5 = PowerColor's Radeon 6700XT US$ 429
due AMD nearly always cheaper than nVidia for the same performance hence my 1st recommendation is =
https://www.amazon.com/PowerColor-Hellhound-Graphics-Raytracing-Infinity/dp/B08Y93KQR4/ref=sr_1_6?crid=OQHBEQ23MWXO&keywords=6700xt&qid=1660098113&sprefix=6700xt%2Caps%2C276&sr=8-6

item 6 = 2*8GB must get RYZEN certified
memory QUALIFIED VENDORS LIST says for example ASRock B550 Steel Legend's
https://www.asrock.com/mb/AMD/B550M%20Steel%20Legend/index.asp#MemoryVM

or whatever word compatible (but do not be fooled)
- extremely important for you newbie not to headache and not to go into expert bios mode to solve timing parameters issues.

item 7 = must get NVMe Gen4 = PCIe4 because 5600x and B550 can make use of it.
eg https://www.amazon.com/s?k=2tb+nvme+gen+4&crid=1ZR8WOF7ID5KQ&sprefix=2tb+nvme+gen+%2Caps%2C292&ref=nb_sb_noss_2

item 8 = your selection ok

I just save your nearly US$ 2000 :)

Hi @nancyj61

September 15th launching Ryzen 7000
see https://www.tomshardware.com/news/ryzen-7000-launching-september-15th


Ryzen 7700x may be US$ 250 ???
see https://www.tomshardware.com/news/amd-zen-4-cpu-pricing-leaked-ryzen-9-7950x-may-cost-over-dollar800


Oh apparently B650 pcie5 is only storage, GPU lanes don't get pcie5
see https://wccftech.com/asrock-b650e-b650-motherboard-lineup-for-amd-ryzen-7000-desktop-cpus-leaks-out/

it's OK I suppose, we're kept reminded that GPU data throughput does not never saturate pcie4, hence we are not lost,

but storage NVMe SSD are able to make full use to pcie5 if the SSD is that fast.... so my reommendation stands, just get B650, not waste the money on X670. Especially not the x670E, unless you're sure you know you will use whatever's extra over B650.
