I recently upgraded from a GTX 1060 to an RTX 4060 Ti and expected a much bigger improvement in gaming performance. While my FPS is better overall, I'm still seeing lower-than-expected frame rates and major drops. I'm upgrading the rest of the system gradually, so I'm wondering how much my older hardware is holding the new GPU back. My current setup is an Intel Core i7-6700, ASRock H110M-ITX/ac motherboard, 16GB of T-Force RAM, RTX 4060 Ti, an older 500W OCZ power supply, and a 500GB Samsung SSD. I mainly play CPU-heavy games such as Counter-Strike 2, Hell Let Loose, BeamNG.drive, and Battlefield 6. Could the processor and platform be causing performance to be almost as disappointing as it was with my GTX 1060?

Check GPU utilization while gaming. If the GPU frequently stays well below 95–100% while one or more CPU cores are maxed out, the processor is likely the bottleneck. CPU usage around 90–100% in games supports that diagnosis, though the old power supply is also worth replacing before installing more powerful hardware.
A platform upgrade would be the most reliable fix. The motherboard and CPU are several generations old, and newer games benefit from more cores and stronger per-core performance. There are unofficial modification routes for fitting newer processors to some older boards, but they require careful research and tinkering and may not be as dependable as moving to a modern platform.
Yes, the i7-6700 can hold back an RTX 4060 Ti quite significantly, especially in CPU-heavy games. The older four-core processor may not deliver frames quickly enough, which can cause stuttering and large FPS drops even though the graphics card is much faster.
