Quick Answer
Yes, 64GB RAM is overkill for pure gaming in 2026. No current game uses more than 20GB of RAM. 32GB (2x16GB) is the sweet spot, handling every game plus background apps with headroom. 64GB only makes sense for content creation, VMs, or heavy multitasking.
There is zero FPS difference between 32GB and 64GB in any game. Once the game has enough RAM, additional capacity provides no benefit. Both configurations produce identical benchmark results.
Our Verdict
64GB is overkill for gaming. No game needs it, and 32GB handles everything with room to spare. Only buy 64GB if you do content creation or run demanding productivity applications alongside gaming.
32GB is the new standard for gaming in 2026. Several modern titles use 14-16GB of RAM, leaving 16GB systems with no headroom for background tasks. The price gap is only $30-50 AUD for DDR4 and $40-60 AUD for DDR5, making 32GB the clear choice.
The best RAM for the Ryzen 7 7800X3D is 32GB DDR5-6000 CL30 in a 2x16GB kit. DDR5-6000 hits the AM5 sweet spot where the Infinity Fabric runs at a 1:1 ratio with the memory clock, giving optimal latency and bandwidth for gaming.
DDR4-3200 and DDR5-5600 perform within 3-5% of each other in gaming with the i5-13400F. The DDR4 platform costs $80-120 AUD less overall. DDR5 only shows meaningful gains with very fast kits (6000+ MHz) that are expensive. DDR4 is the value choice.
