Is tuned DDR4 still a good choice for esports gaming?

Yes, tuned DDR4 is still the right move for esports. For Valorant and CS:GO, the difference between tuned DDR4 and DDR5 in average FPS is negligible—single-digit percentages at 1080p low settings. Your money is better spent on a faster GPU or CPU, and most high-refresh-rate players are still crushing it with 3600MHz CL16 or B-die kits. If you already own a good DDR4 board and kit, swapping just for these games is pointless.
