testing cpu

Not really, a cpu is a complex peice of logic circuits. The only real test is to put it onto an acceptable motherboard fully populated with known good memory and chipsets/cards and see if it powers up. If it does then you can run bench tests software to compare your results with normal functionality.

The most cost effective way to test a CPU is with a known good motherboard.

Yes, there are test systems designed to test CPUs and other integrated circuits. The starting price for a test system is over $100,000 US.
Figure on over $500,000 for a system that can perform a thorough test on a CPU.

In regards to tec_wiz03 answer...some good benchmark software and "burn-in" tests for CPU and other system components:
