At 1440p, performance improves significantly with most games exceeding 100 FPS. This remains the sweet spot resolution for this pairing, delivering smooth gameplay without overtaxing either component.
The 6% bottleneck manifests in CPU-intensive scenarios, particularly in games with heavy physics or AI processing. At 4K, the GPU limitation keeps the bottleneck minimal.
AM4 Upgrade Path
For existing AM4 system owners, this configuration makes excellent sense. You likely already own the motherboard and DDR4 memory—just add the RTX 5070 and enjoy modern gaming performance.
The 5600X can also be upgraded to a 5800X3D if you want to reduce the bottleneck further without platform changes. The X3D's massive cache dramatically improves gaming performance on AM4.
This staged approach lets you maximize existing hardware before eventually transitioning to a new platform. The RTX 5070 will serve well on future systems too.
New Build Considerations
For new builds, AM5 with a Ryzen 5 7600 offers better value and performance with a similar price tag. The newer platform provides DDR5 memory, PCIe 5.0, and a longer upgrade path.
Building new on AM4 in 2025 only makes sense if you're getting excellent deals on used components or have specific compatibility requirements. Otherwise, AM5 is the better foundation for a new system.
At $999, this build assumes some component reuse or budget deals on AM4 hardware. Pure new-build costs would be similar to AM5 alternatives.
System Requirements
A 550W quality power supply handles this efficient build. Both components are power-modest, keeping overall consumption reasonable.
The stock AMD cooler works, though a budget tower cooler improves thermals and noise. The 5600X runs cool enough that expensive cooling isn't necessary.
16-32GB of DDR4-3600 CL16 memory is optimal for the 5600X. Higher speeds offer diminishing returns on Zen 3.
B450 or B550 motherboards work well—most are mature and affordable, with good feature sets for the price.
Final Verdict
The RTX 5070 and AMD Ryzen 5 5600X create a capable gaming build, particularly for AM4 upgraders. The 6% bottleneck is reasonable, though newer platforms offer better overall value for new builds.
At $999, this build is ideal for AM4 owners upgrading their GPU, budget builds using existing DDR4 memory, and users wanting to maximize AM4 platform lifespan. The 5600X proves that last-gen processors still handle modern GPUs respectably.
