Is it possible to find a website that will tell you benchmarks based on parts that you put in? Say like a pcpartpicker website but it also will tell you the benchmarks for that build?

Those don't exist, but you can look up benchmarks for individual parts like GPU and CPU.
I'd recommend:
-Anandtech
-Guru3D
-HardwareUnboxed and GamersNexus on Youtube
