He wants to know how his OC 5300 compares to a more expensive stock 7XXX/8XXX series cpu.
It's hard to say given all of the possible variables, but, I would suggest running some common CPU intensive benchmarks such as the Dhrystone/Whetstone tests from SiSoftware Sandra, Kribi Bench and others. Running 3D mark vantage and some cpu intensive gaming benchmarks will also help you out in finding your OC'ed cpus place.
