Yes, overall the intel cpu is much better and you picked the better video card as well.I'm also assuming by the fact you only mentioned stuff on the more expensive setup that its better?
Because its old and outdated. Benchmarks here. http://cpu.userbenchmark.com/Compare/Intel-Core-i5-6500-vs-AMD-FX-8320/3513vs1983why wouldn't the 8 core processor be better?
yes.PSU meaning power supply right?
Due to IPC. Basically each core on the 8 core is much slower than each core on the i5, making the i5 faster.why wouldn't the 8 core processor be better?
