I'm putting together my first gaming PC with a Ryzen 5 7600 and an RTX 5070, but I'm unsure which memory option makes the most sense for my budget. I can currently afford one 16GB DDR5-6000 stick, though I may be able to find a 2×8GB DDR5-5600 kit for significantly less. Another possibility is buying a single 16GB DDR5-5600 stick and adding more memory later. How much performance would I lose by choosing 5600 instead of 6000, and is dual-channel memory more important than the higher speed?

Compare the actual prices before deciding. The graphics card and processor will have a much larger effect on gaming performance than the small difference between DDR5-5600 and DDR5-6000. Also, avoid planning around four memory sticks on a DDR5 system, since two sticks are generally easier to run reliably.
If you choose one 16GB stick now, get a model and memory kit that should be easy to match later. Mixing different modules, timings, or memory chips can sometimes cause stability issues. The performance penalty from 5600 versus 6000 is fairly small, while dual-channel operation can make a more noticeable difference depending on the game.
I’d avoid buying one stick if possible. A single 16GB stick will work, but it can reduce gaming performance compared with two matched sticks. If you buy 2×8GB now, you could later replace them with a 2×16GB kit when you need 32GB, rather than mixing different kits.
My concern is that replacing the kit later could be expensive, but I’ll compare the prices before deciding.
For a Ryzen 5 7600, DDR5-6000 is a nice target, but it isn’t mandatory. Prioritize capacity and two matched sticks over a small speed increase. If you can stretch to 2×16GB DDR5-6000 without sacrificing other important parts, that would be the best long-term option; otherwise, 2×8GB DDR5-5600 is a reasonable budget choice.
The difference between DDR5-5600 and DDR5-6000 usually isn’t very noticeable, especially compared with the difference between running one stick and two sticks. If those are your only choices, 2×8GB DDR5-5600 will generally perform better than a single 16GB stick because it runs in dual channel. Just buy a matched kit from a reputable brand.
That makes sense. I was focused on getting 6000 because I assumed the speed difference would be much larger.
I’ll look for a common model from a reliable manufacturer so an eventual upgrade has a better chance of working smoothly.
