He compares CPUs and GPUs against large graphs which contain older GPUs and CPUs to decide if you need to upgrade. Also, shows things like thermals and power consumption. Good if you want a rough estimate of a certain computer part performance.

Huge fan, he has delivered unbiased information for years now. Very trustworthy source, glad userbenchmark is considering his inputs.
