Should I upgrade from single-channel 8GB to dual-channel 16GB for CS:GO and Valorant?

Yes, if you’re moving from single-channel 8GB to dual-channel 16GB (2x8GB), you’ll see a noticeable lift in CS:GO and Valorant. The hero isn’t the extra capacity – it’s the dual-channel memory bandwidth. In CPU-bound esports titles, single-channel memory can bottleneck the CPU by 20–30%, and going dual-channel lets the CPU feed data faster, directly improving frame rates. If you already have 16GB in dual-channel, more capacity won’t help much.
