I'm planning a new PC mainly for competitive Fortnite at 1720×1080 with low settings and Performance Mode. I'm aiming for roughly 240–260 FPS in Creative, while understanding that endgame FPS will be lower. I also want to stream or record, and after several months I'll mostly use the system for coding, 3D modeling, and computer science projects. My current parts list is a Ryzen 5 7600X, 16GB of TeamGroup T-Force Delta RGB DDR5-6000 CL38, and an Intel Arc B580. I found a used 32GB kit consisting of two DDR5-5600 CL38 sticks, but I'm hesitant because of the condition, price, and long shipping time. The alternative is buying a used Ryzen 5 7600X3D while keeping only 16GB of RAM. Is the 7600X3D worth prioritizing for competitive Fortnite, or would 32GB be the better choice for streaming, multitasking, and future use?

I’d choose 32GB of RAM before upgrading to the 7600X3D. Sixteen gigabytes can work for Fortnite by itself, but streaming, recording, browser tabs, launchers, and development tools can push you into using the page file. That can cause stutters even if the average FPS looks fine. The 7600X is already a strong gaming CPU, and 32GB will make the whole system more comfortable for coding and 3D work.
At 1720×1080 and competitive settings, the CPU will matter more than the B580 once you’re chasing very high frame rates. The 7600X3D would likely improve lows and consistency in Fortnite, but it isn’t necessary for the system to perform well. I’d only take that route if you care more about maximizing competitive FPS right now than about streaming, multitasking, and your upcoming workstation use.
A 240Hz target is ambitious, especially in busy matches, so don’t judge the build only by Creative-mode FPS. Stable frametimes and the right settings matter more than a peak number.
Avoid buying used memory that takes a month to arrive unless the savings are substantial and you have a clear return option. DDR5-5600 CL38 is perfectly usable, but it’s a small step down from a properly tuned DDR5-6000 kit. Ideally, buy a new 2×16GB kit from a reputable seller, preferably around DDR5-6000 with a reasonable latency, and enable the memory profile in the motherboard firmware.
The Arc B580 should be more than adequate for 1080p Fortnite at low settings, although competitive performance can depend on drivers and the game’s rendering mode. For your use case, I’d prioritize 32GB of RAM, keep the 7600X, and upgrade the CPU later only if testing shows that it is limiting your frame rate. That gives you a more balanced machine for streaming and future coding or 3D projects.
Even with a lightweight browser and a Linux dual-boot, 32GB is a useful safety margin. You can always replace the CPU later, but I wouldn’t intentionally build a new system around 16GB if the extra memory is reasonably affordable.
