Need urgent assistance picking the right CPU, power supply, RAM, and motherboard?
The single-threaded speed of the 3rd generation AMD matches that of Intel. The benchmark results confirm this; while Intel still leads overall, the gap is minimal—under 1%. For someone starting with a 1150 system, upgrading to any modern CPU will significantly boost performance. Explore the reasons to choose AMD now: it's more affordable, uses 7nm technology, runs cooler, offers better performance per clock, and supports future upgrades. Intel has been stuck on 14nm for too long. AMD also provides PCIe 4.0, and it addresses security concerns with Spectre and Meltdown fixes. Previously, support for AMD was limited, but now it's strong, with 75% compatibility. This shift reflects a fair perspective, as seen in discussions where even long-time Intel users are considering AMD for their builds.
Hi everyone, thank you all for your input, particularly those staying on the discussion thread. I truly value your insights. I dedicated a lot of time last night reviewing the research data, and now I’m focusing on this: PCPartPicker Part List Type Item Price CPU AMD Ryzen 7 3800X 3.9 GHz 8-Core Processor $338.99 on Amazon Motherboard, Gigabyte X570 AORUS PRO WIFI ATX AM4 Board $229.99 on Amazon, and G.Skill Trident Z Neo 32 GB DDR4-3600 Memory $159.99 on Newegg, and Corsair RMx 850W ATX Power Supply $129.99. Total comes to $858.96.
Important notes: I’m setting a $1000 limit here since this is personal spending, not company funds. Otherwise, I’d go for premium options! Reliability and budget play big roles in my choices. Key questions: Am I risking myself by saving ~$57 and picking the 3800X instead of the 3900X? I’m not very familiar with AMD CPU depreciation. I chose DDR4-3600 Memory after some videos and articles highlighted Ryzen’s need for fast RAM. Is that excessive? Not enough?
I’m also wondering if I should consider 3666 or 3733 MHz. I went with Corsair 850W because of their 10-year warranty and the extra power capacity. Still unsure if upgrading later would be worth it (~17.39% more).
Thoughts? Do I really need to check 3666 or 3733 MHz? I picked the AORUS PRO WIFI X570 AORUS PRO because it was the most affordable among AORUS with Wi-Fi and two M.2 slots. I’m weighing AORUS PRO ULTRA now due to an extra M.2 slot, but it might add about 17.39% more cost.
Should I downgrade any part to save on the 3900X? For example, switching to a 3200 MHz DDR4, using a 650W power supply, etc., to offset the extra expense?
Feedback: I’m more focused on real-world performance than tiny differences. That’s why I went with the 3800X instead of the 3900X. The price difference is big, but I’m not sure if it’s worth it. Also, I worry that spending over $500 on the 3900X might hurt my budget in a couple of years if prices drop.
I really appreciate all your effort and the detailed info you shared—it made this list a lot clearer. Thanks for your help!
If you're targeting a Ryzen 7, opt for the 3700X rather than the 3800X. Cut costs since the 3800X is merely a marginally upgraded version of the 3700X. I believe your choice should lean toward a 3900X, as it will better suit your needs and you'll see the advantages. You also have the flexibility to upgrade later from a 3700X to a 3900X or even a 3950X if you decide to save more.
3600MHz RAM is crucial for performance; exceeding it (beyond 3733MHz) can reduce efficiency because the infinity fabric ratio shifts from 1:1 to 2:1, cutting your CPU's speed in half.
Power consumption matters at 850W—only necessary if you plan to use SLI or upgrade your GPU to a more demanding model. Otherwise, sticking with the recommended power levels should suffice.
For budget builds, the ASUS TUF WiFi or ASUS Prime Pro are solid picks. Both offer reliable power delivery, Wi-Fi, and affordability. The Prime Pro model versus Aorus Pro isn't clear to me.
Up to 3200MHz RAM is acceptable if you're targeting a 3900X, as it won't significantly affect performance unless you're aiming for higher speeds. Ultimately, the decision rests with you.
Hey @GeLi, thanks for your response! I was considering 3800X as a middle ground between 3700X and 3900X. However, if it were strictly between those two, I’d probably switch to 3900X. The 3600 MHz model seems ideal for me. I’m also wondering about the timing—I’ve noticed a pattern in my searches. My initial pick (link) is 160 USD, but I don’t need the RGB details. The timing options are 16-19-19-39. Which one fits better for the 3900X? Would picking a less optimal timing hurt me? I stayed with my GTX 760 for about four years, planning to swap it out before upgrading to a GPU that never happened—so I got a 2080. I think I’ll stick with the 2080 until it’s no longer useful or until a better choice appears. So, I probably won’t need the 850W 80 PLUS Gold. Instead, I’ll look into lower wattage PSUs rated Gold or higher. I have several storage devices (three SSDs and one HDD), and I notice 850W PSUs usually have more SATA ports. Like my setup, I’ll likely use an M.2 SSD for booting and switch some storage drives to a dedicated SSD later. I assume the other two M.2 drives are just for backup. Based on your advice, I’m thinking about swapping out my current PSU and graphics card for something else—so long as it doesn’t restrict the number of SSDs or drives I use. This should help me save money for the 3900X. Thanks!
