Total Performance Rating
The TPR graph is a combination of all our benchmarks in which NVIDIA and ATI are on an even playing field.
The TPR number is a combination of:
3DMark Vantage, Heaven Benchmark V2, Resident Evil 5, Tom Clancy's H.A.W.X., Mafia 2 (PhysX Off), Lost Planet 2, Aliens vs. Predator, Final Fantasy XIV, Street Fighter IV, Far Cry 2, Batman: Arkham Asylum (PhysX Off) and our four High Quality tests which include Mafia 2, Aliens vs. Predator, Street Fighter IV and Far Cry 2.
All of the benchmark results achieved are then combined into a single number. As this graph will grow over time and cards won't be re-tested, next to each model you'll find the driver version that was used when the card was benchmarked.
Overall the TPR is strong and the setup manages to outperform the overclocked GTX 480 Super OC (when OCed even further). The only reason it doesn't win overall is because of the Final Fantasy XIV scaling issue. Not only does it not improve, but it goes backwards.
If the score was about the same as the single GPU performance it would pull out a win. If it improved as much as the GTX 460 SLI setup does then it would be easily on top of the leader board. It means we just have to work a little harder.
