I'm building a gaming PC and comparing a single 32GB DDR5 stick with a 2x16GB kit. The single-stick option would save quite a bit of money, but I'm unsure how much performance I'd give up. I'm considering 2x16GB Patriot Viper Elite 5 DDR5-6000 CL30 or 1x32GB G.SKILL Aegis DDR5-5600 CL36 with Intel XMP/AMD EXPO. Is the cheaper single stick worth considering, or should I prioritize dual-channel memory?

The 2x16GB kit is the better choice for gaming because it enables dual-channel operation. Depending on the game and whether you’re CPU- or GPU-limited, the difference can range from nearly nothing to around 10–25%, with noticeably better 1% lows in some titles. Normal desktop use usually won’t feel different.
I’d pick the Patriot 2x16GB kit here. Besides dual-channel performance, DDR5-6000 CL30 is faster and has lower latency than DDR5-5600 CL36, making it a stronger fit for a gaming build. If you buy one 32GB stick now, make sure adding a matching module later is realistic.
A single DDR5 stick can still work, and DDR5’s architecture makes the penalty less severe than it was with older memory generations. However, you’re still giving up bandwidth, so two matched sticks are preferable unless the price difference is unusually large or you plan to add a second stick soon.
