Reduced performance

[DrDinosaur]

Code:

hashcat (v3.20) starting in benchmark mode...

* Device #2: Old CUDA chipset 3.0 detected, OpenCL performance is reduced.
             For ideal hashcat performance on NVIDIA GPU you need Shader Model 5.0 or higher
nvmlDeviceGetFanSpeed(): Not Supported

OpenCL Platform #2: NVIDIA Corporation
======================================
* Device #2: GRID K520, 1009/4036 MB allocatable, 8MCU

I'm getting this message when I run the benchmark. Does this error have to do with the GPU itself (meaning I would have to change to a new physical GPU), with a driver, or something else? The driver version is 367.57.

Thanks.
