I'm considering upgrading from a Ryzen 7 3700X and moving to the AM5 platform. I currently use an RTX 3070, but I'm planning to pair the system with an RX 9070 next year. The Ryzen 5 7600X3D bundle looks appealing, especially for competitive games where I want the highest possible frame rates. However, the bundle only includes one 16GB DDR5 memory stick. Would running single-channel RAM noticeably reduce performance until I add another stick, and is it better to wait and buy a complete 32GB kit instead?

For a new build, the 7600X3D is a strong gaming choice, but upgrading from a 3700X may not feel dramatic in every game. Your current system is still capable of high frame rates, so waiting until you can buy the CPU, motherboard, and a proper memory kit together could make more sense. Selling the old parts could also help offset the cost.
The 7600X3D should pair very well with an RX 9070, especially at high refresh rates and competitive settings. The bundle is a reasonable way into AM5, although a 7800X3D package with 32GB of RAM could offer better long-term value if it fits your budget. Running one memory stick will reduce performance somewhat because you’ll be in single-channel mode, but the CPU itself should still perform well.
If maximum FPS is the goal, don’t plan on using the included 16GB stick by itself for long. Buy a matched 2-stick DDR5 kit, ideally 32GB, rather than adding a random second module later. A separately purchased stick might work, but mixed memory can force lower speeds or cause stability problems, particularly with DDR5.
Using an identical module doesn’t automatically guarantee trouble—sometimes matching sticks run perfectly—but a factory-matched kit is still the safer choice for getting the rated speed and stability.
