PCMark Vantage Testing
Both EVGA products turned in exceptional performances during PCMark Vantage testing, which happens to be the most comprehensive testing we run for general system performance. The P55 SLI led the pack with an overall score of 7966, while the P55 Classified finished third at 7902 PCMarks. Finishing second was Intel's DP55WG with a score of 7927, once again demonstrating competitive performance at the lowest price point of the round up. That said, there is only about a 2% to 5% spread in performance metrics between any of the boards we tested here.
