Hey im gonna buy i5-12400f and rx6700xt but i hesitate between ddr5 16gb with h610 motherboard and ddr4 32gb with myb b550 motherboard. What do you think? I think i should go with ddr5 cause myb its better for future and longer duration.
Depends on what you're using your PC for.
If it's gaming - DDR4, especially since you'd have it 32GB.
If number crunching or any other task that requires fast RAM frequency - DDR5. 16GB wouldn't be that much for workstation build. 64GB and now we're talking.
