Is Upgrading Your CPU or GPU the Key to Unlocking Better VR Performance?
The big question is would be upgrading your CPU or GPU help virtual reality (VR) gaming performance? Virtual reality has transformed gaming immensely, delivering immersive experiences that were once unimaginable with stereoscopic depth perception and 260 spherical point of view. However, upgrading your CPU or GPU with the wrong focus may prevent real maintaining smooth VR gameplay, especially in resource-intensive simulators like X-Plane and DCS World, is a significant challenge. For those with setups like the Ryzen 5 5600X and RTX 3070, the question arises: should you upgrade your CPU or GPU to enhance performance? Let’s dive into the details to identify the most effective upgrade path for VR enthusiasts.
Personal Gaming Trauma – What to Do? Upgrading Your CPU or GPU?
I’m a fanatical VR pilot in DCS World as well as X-Plane 11/12 and I’m frustrated by my systems performance. These and other simulators and games continue to demand more and more powerful components in our gaming PC’s. My performance in these is average at best and it works but I want more! Am I greedy?
I am finding personally that my own system, which is a RYZEN 5 5600x, NVIDIA RTX 3070 (8GB) complimented with 64 GB DDR4 3200 MHz ram plus my various SSDs are struggling to deliver the true experience I see others achieve. If you’re wondering about the 64Gb of ram it’s not required for X Plane or other games but, DCS World on a busy multi player server eats up the RAM at 32 Gb and it grinds to a halt. I regularly see 35-38 GB of RAM usage so i [picked up the other 32GB a while back and problem solved.
I honestly posed this exact question to Chat GPT and the included is the actual reply expanded into a blog post so all of us in this precarious position. Its uncomfortable to be teetering on a decision so having more information before being disappointed with a bad decision is a good idea! I hope the advice helps you as well before we get the wallet or credit card out to try and resolve it.
Resolution is the first question You Must Answer!
Upgrading your CPU or GPU – Recommendations for VR Enthusiasts
Based on my current setup and gaming preferences, the advice is as follows:
- If Keeping the Ryzen 5 5600X:
- Upgrade to an RTX 4070 or consider waiting for the RTX 5070.
- Optimize in-game settings and leverage features like DLSS or FSR (FidelityFX Super Resolution) to maximize performance.
- If Upgrading the CPU:
- The Ryzen 7 7800X3D offers transformative performance improvements, especially for simulation-heavy gaming.
- Ensure your motherboard is compatible with the AM5 socket before proceeding with the upgrade.
- For Long-Term Optimization:
- Combining a Ryzen 7 7800X3D with an RTX 4070 or newer GPU ensures the best balance for CPU- and GPU-intensive tasks, delivering smooth VR performance.
- However, because VR is highly dependent on GPU performance, upgrading to an RTX 4070 or waiting for the RTX 5070 is likely to yield more noticeable results.

Resolution and Its Impact on Upgrade Decisions
Upgrading your CPU or GPU – 1080p Gaming
At 1080p resolution, gaming performance is often CPU-bound, as the GPU has less strain rendering fewer pixels. In this scenario, upgrading the CPU to a Ryzen 7 7800X3D is the most effective path if you’re encountering frame rate drops or stuttering. The RTX 3070 should remain capable for most titles, including VR, at this resolution. – CPU UPGRADE OK!
Upgrading your CPU or GPU – 1440p Gaming
At 1440p, the workload begins to balance between the CPU and GPU. If your current setup struggles, upgrading the GPU to an RTX 4070 can provide a noticeable boost in VR performance and visual quality. The CPU upgrade remains relevant if your primary games are CPU-intensive simulations. – GPU UPGRADE BEST ADVICE.
Upgrading your CPU or GPU – 4K Gaming and VR
At 4K resolution or in VR, the GPU becomes the critical component. The RTX 3070 may fall short, especially in demanding VR scenarios. Upgrading to a more powerful GPU like the RTX 4070 or 5070 ensures smoother performance and better support for high-resolution textures. However, the CPU should not be overlooked if your games heavily rely on processing power, as bottlenecks could still arise. – GPU UPGRADE Priority but may also require a CPU UPGRADE depending on performance.
Understanding VR Hardware Demands
VR gaming places unique demands on hardware, requiring the simultaneous rendering of high-resolution visuals for two displays (one per eye) while maintaining high frame rates. This ensures a seamless and motion-sickness-free experience. Key hardware components impacting VR performance include:
- GPU (Graphics Processing Unit): Handles rendering of high-resolution, high-refresh-rate graphics.
- CPU (Central Processing Unit): Manages game logic, physics, and AI calculations.
- RAM: Supports smooth multitasking and rapid data access.
- Storage: Affects loading times but has minimal impact on real-time performance.
Understanding the interplay between these components is critical for identifying and addressing system bottlenecks.

- DLSS 3: Adds advanced frame generation for supported games, significantly boosting performance.
For those willing to wait, the RTX 5070 (anticipated in 2025) is expected to deliver even greater architectural improvements and efficiency gains.
AMD RADEON 9070 is an Option!
With the anticipated release of the AMD Radeon RX 9700, the GPU market is poised for another shake-up, especially for enthusiasts focused on flight simulators like X-Plane 12 and DCS World. These titles rely heavily on raw rasterization performance and VRAM capacity, areas where AMD’s RDNA 3 architecture shines.
Unlike Nvidia’s offerings, which emphasize features like DLSS and frame generation, these technologies are less impactful in X-Plane 12 and only partially relevant in DCS World (where DLSS is supported but frame generation is absent). The Radeon RX 9700 is expected to deliver competitive performance in these scenarios, offering excellent value with potentially higher VRAM and better price-to-performance ratios.
If AMD maintains its reputation for efficiency and competitive pricing, the RX 9700 could emerge as the smarter choice for sim enthusiasts looking for powerful hardware without paying a premium for features, they’re unlikely to utilize. Personally, as a dedicated Nvidia Fan boy, I’m seriously considering jumping to AMD RADEON 9070. If previous history of price to performance in direct rasterization are repeated and benchmarks and reviewer videos on YouTube confirm this, it seems a no brainer to me at the moment. Only time will tell.
Deciding Between a CPU or GPU Upgrade
Choosing between a CPU and GPU upgrade depends on several factors:
- Identifying Bottlenecks:
- Use diagnostic tools like MSI Afterburner or CapFrameX to determine whether your CPU or GPU is hitting maximum utilization during gameplay.
- Game-Specific Needs:
- Simulators like X-Plane and DCS World benefit significantly from robust CPU performance, particularly with technologies like 3D V-Cache.
- VR overall leans heavily on GPU capabilities for rendering and maintaining frame rates.
- Budgetary Considerations:
- A CPU upgrade (e.g., Ryzen 7 7800X3D) may require additional costs, such as a new motherboard.
- GPU upgrades, such as moving to an RTX 4070, often deliver more immediate and noticeable performance gains in VR.
Recommendations for VR Enthusiasts
Based on your current setup and gaming preferences, here are our recommendations:
- If Keeping the Ryzen 5 5600X:
- Upgrade to an RTX 4070 or consider waiting for the RTX 5070.
- Optimize in-game settings and leverage features like DLSS or FSR (FidelityFX Super Resolution) to maximize performance.
- If Upgrading the CPU:
- The Ryzen 7 7800X3D offers transformative performance improvements, especially for simulation-heavy gaming.
- Ensure your motherboard is compatible with the AM5 socket before proceeding with the upgrade.
- For Long-Term Optimization:
- Combining a Ryzen 7 7800X3D with an RTX 4070 or newer GPU ensures the best balance for CPU- and GPU-intensive tasks, delivering smooth VR performance.
Conclusion
Whether to upgrade your CPU or GPU depends on the limitations of your current system and your budget. While the Ryzen 5 5600X is a reliable performer, its constraints in CPU-heavy VR scenarios may warrant upgrading to the Ryzen 7 7800X3D. However, because VR is highly dependent on GPU performance and that’s my personal focus, upgrading to an RTX 4070 or waiting for the RTX 5070 is likely to yield more noticeable results. This seems to be the answer for me personally.
By carefully analyzing system bottlenecks and leveraging available benchmarks, you can make an informed decision to elevate your VR experience, whether you’re exploring the skies in X-Plane or engaging in intense aerial combat in DCS World.
