Synthetic BenchmarksWe first converted the obtained scores/FPS for each benchmark to a percentage in comparison to the highest score (=100%), we then averaged all the benchmark scores per resolution/IQ and the results are put into these charts. So these are relative performance charts in % to the fastest card. (

In the synthetic benchmarks without Antialiasing, we can see the GTS 450 being placed between the GeForce GTS 250 Deep Green from Gainward and the XFX Radeon HD 5770; the difference between the GTS 450 and the 5770 is bigger as the resolution increases.
When we add 4xAA filtering, it seems the situation repeats itself, the GTS 450 being placed in the same position and the performance difference between the GTS 450 and the 5770 increases with the resolution.
