I'm choosing between two similarly priced gaming builds and would appreciate some advice. Build 1 uses a Ryzen 5 7500F, RX 9070, 16GB DDR5-6000 CL30 in a single stick, and an Asus Prime B850M-K motherboard with two RAM slots. Build 2 uses a Ryzen 5 7500X3D, RX 9060 XT 16GB, the same 16GB single-stick memory configuration, and an Asus B850 MAX Gaming WiFi W motherboard with four RAM slots.
I originally considered the 7500X3D because its extra L3 cache might help offset the performance loss from running memory in single-channel mode. Unfortunately, good memory kits are difficult to find locally, and the practical option right now is one 16GB stick. I plan to add another matching 16GB stick in roughly five or six months.
I currently play at 1080p but expect to move to a high-refresh-rate 1440p monitor soon. My main games are The Finals and Marvel Rivals, along with AAA games such as Cyberpunk 2077 and Elden Ring. I also plan to keep the graphics card for at least four years.
The RX 9070 is clearly the faster GPU, but I'm concerned that pairing it with the 7500F and single-channel memory could hurt high-refresh-rate performance and especially 1% lows. Is the stronger GPU still the better choice, or would the 7500X3D and RX 9060 XT provide a more balanced experience?

I’d choose the Ryzen 5 7500F with the RX 9070, especially since you’re moving to 1440p. The single memory stick will reduce performance compared with dual-channel, but it doesn’t make the system unusable, and adding a second matching stick later should fix that. The RX 9070 is a much larger upgrade than moving from the 7500F to the 7500X3D in most GPU-limited games.
Don’t choose the more expensive motherboard just because it has four memory slots. A two-slot board is perfectly fine if you’ll eventually run two 16GB sticks, and the cheaper board should still be suitable for a future CPU upgrade. Put the savings toward the stronger graphics card or the second memory stick.
AM5 memory support can become more difficult with four populated slots, so having four slots isn’t automatically better. Two matched sticks are usually the simplest configuration.
The single-channel setup will affect minimum frame rates more noticeably in CPU-heavy esports titles, but it’s a temporary limitation rather than a reason to downgrade the whole system. If the two builds cost about the same, I’d take the 7500F and RX 9070, install the second matching RAM stick as soon as practical, and use upscaling or adjusted settings if needed in especially demanding games.
For 1080p esports gaming, the 7500X3D and RX 9060 XT 16GB combination is already very capable. The extra cache can help in CPU-limited games, and the 9060 XT should handle your current games at high settings. However, once you move to 1440p, the RX 9070 build makes more sense and gives you considerably more headroom for demanding games over the next several years.
That was my main concern: whether the single-channel penalty would be large enough to undermine the stronger GPU in esports games. I’m planning to add the second stick within a few months.
