I Use Toms Hardware https://www.tomshardware.com/ Over clockers https://www.overclockers.com/ For Hardware Comparison https://www.productchart.com/laptops/ https://www.cpubenchmark.net/laptop.html For GPU comparison http://gpuboss.com/compare-gpus https://www.videocardbenchmark.net/

All Benchmarks so you can decide if the extra cost of a CPU and/or GPU is worth the price
