Yes, there are several websites and software tools that can help you check the clock speed of a used computer to determine if it will handle large Chief files well. Here are a few options:
PassMark (https://www.passmark.com/): PassMark provides a popular benchmarking software called PerformanceTest, which includes a CPU test that measures the clock speed of your computer's processor.
CPU-Z (https://www.cpuid.com/softwares/cpu-z.html): CPU-Z is a free utility that provides detailed information about your computer's hardware, including the clock speed of your processor.
Speccy (https://www.ccleaner.com/speccy): Speccy is another popular free utility that provides detailed information about your computer's hardware, including the clock speed of your processor.
UserBenchmark (https://www.userbenchmark.com/): UserBenchmark is a website that allows you to compare the performance of various computer components, including CPUs.
It's important to note that clock speed is just one factor that determines a computer's performance, and other hardware components such as RAM, graphics card, and storage drive also play a significant role. So, it's recommended to consider the overall specifications of the used computer, including CPU, RAM, graphics card, and storage, to assess its suitability for running Chief Architect software with large files. Personally I would never suggest to go for used computers because there is go guarantee, warranty or any kind of replacement or return policy unlike the first hand. It's better to buy new one. Nowadays there are better pcs in cheaper price as well.
