Update system requirements
On the system requirements page, CPU requirements state that "the specific CPU model listed above would need to be used when running the encoder", but there is no "specific CPU model" mentioned above. The paragraph then goes on to say the encoder will run on any 5th gen Intel CPU (Broadwell).
The current wording is unclear as to which CPU generation is the minimum requirement, or rather which x86 ISA extensions are mandatory. Cursory look over the project sources show that there are SSE2 sources, which should be unnecessary if AVX2 (which is supported by Broadwell) is the minimum.
