    Flawless CPU upgrade with great temps and performance

    Upgraded from a 5600x. Effortless installation as always with AMD. Flashed the BIOS to newest version and had new chipset drivers downloaded. Back up your primary drive beforehand folks. Also remember that changing the cpu will disable your Windows login method and you will need to sign back in with your Microsoft account password so track it down before you do the swap. After the first login you can change back to a PIN or whatever.Huge improvement in games, the smoothness is very noticeable. I only play wow, pubg and civ 5 so not the most demanding games but in wow I saw Silvermoon fps jump

    Way Better Than Expected

    I've been holding onto my AM4 system for about the last six years running a 3900x 12-core since day one. At the time I built this, I felt my 3900x was more than plenty good enough for my particular needs as at the time I built it, I needed more cores for multitasking and gaming wasn't a priority, but as the years passed, I've shifted more into playing games and I was quickly realizing the 3900x was becoming an issue in frame rates. Games stuttered a lot from low 1% frame rates and it got to the point it was driving me crazy. Almost to the point I didn't even want to game as much because of the

    Huge Gaming Upgrade for AM4

    I upgraded from a Ryzen 7 5700X to the 5800X3D and the difference in games is way bigger than I expected. The biggest improvement is not just the average FPS, but how much smoother games feel overall. Monster Hunter Wilds, Fortnite, and other CPU-heavy games feel noticeably more stable, especially with better 1% lows and less stutter, and even some more gpu heavy games run noticeably smoother as well.It does run hot at stock settings, so I would definitely recommend good airflow and a decent cooler. In my case, once I fixed my case fan settings and used a light undervolt/power limit, it ran mu

    The best AM4 upgrade I could ever make. AM5/AM6 can wait for bit now!

    This is the best AM4 CPU hands down. I got a +60 FPS increase in all my games, I no longer have to change settings for an hour to have a 60+ FPS experience, this is amazing. People who complaing about the temps using the Carbice Ice Pad that comes with it, performance is better with every thermal cycle, meaning that every time the PC gets hotter and cools down, the pad gets performs better. At first I had 80 degrees playing RDR2, and a week and a half later, the CPU temps never go higher than 65 degrees without overclocking and undervolting. Installation is obviously as easy as it is with othe

    Great upgrade for 4K AM4 gaming

    Even at 4K resolution, the 5800X3D still finds ways to shine!It handles 4 sticks of Corsair Vengeance C18 RAM totaling 64GB while running at 3200mhz. It can't really handle 4 sticks at 3600mhz, but thats an AMD thing honestly.Thermals? She runs hot.I used Corsair XTM70 as thermal paste. During idle the chip will sit just shy of 60C and during gaming will sit between 70C-80C. This is with a Corsair Titan 360 RX AIO with a Push-Pull fan setup; fans and pump set to balanced for AIO. Water temps sit comfortably at 31C during gaming, so while the 5800X3D is designed to run hot the AIO doesn't sweat

    Still one of the best gaming CPUs for AM4

    I’ve been using the Ryzen 7 5800X3D for gaming and it has been a great upgrade for my AM4 system. It’s definitely one of the best options you can get if you want to keep your existing AM4 motherboard and DDR4 memory instead of replacing the whole platform.Gaming performance is excellent, and the extra 3D V-Cache really makes this CPU stand out. For a gaming-focused PC, it still has plenty of performance even compared with newer CPUs.One thing I would recommend is using a decent CPU cooler. With proper cooling, I haven’t had any temperature issues during normal gaming use. Power consumption als

    Faster than what I had

    Is quick but runs warm and voltage shifts cause fans to jump and drop in ramp. Manual curve is a must and even then expect jumps with just background actions.. Runs quieter and more stable while gaming.

    Worth the upgrade to stay on DDR4 Motherboard and rams, considering this is the best of the best.

    The item came fast and work how it was supposed to, It's fast and stronger that my old CPU. I think it's worth it for the price considering staying on ddr4 motherboard with spending a lot of money upgrading everything to ddr5. The processing is good for multitasking for surfing or gaming, and installation is easy as any CPU installation is. So far, no overheating so cooling and thermals are doing fine.
