Conclusion: Performance Summary: In comparison to the previous flagship V8800, the new FirePro V9800 showed a slight performance increase. During testing, the card performed about 2% faster than its sibling due to the 25MHz core clock increase. Clearly, our test suite does not show the advantage the card's larger memory capacity over the V8800. But the V9800 was impressive during GPGPU testing, as it came in 103% faster than the Quadro 5000, and 48% better than the 6000.
Pros: Excellent performance, Six monitor support, 4GB GDDR5 onboard memory, Low idle power consumption, Runs cool and quiet
Cons: Expensive, Incremental performance increase over V8800
