Overclocking
We used Call of Duty 2 and Quake4 to highlight SLI performance increases with the XFX XXX Edition. We use those same titles to show clock scaling when the EVGA is pushed to its current limits. Watercooling not only allows you performance in relative silence, but there's also the potential to run higher overclocks than possible on air. Remember in the preview we showed you that EVGA had validated the card to run at 612/905 using the air cooler. With the waterblock attached, 638/920 was possible. Here are the results in the aforementioned benchmarks.
You can see the clock step when further overclocked to those levels, using RivaTuner, here.
Call of Duty 2
When pushed that bit higher, the EVGA carries on scaling well with its frequency increases, as expected.
Quake 4
The same again, the EVGA able to pull out, on average, an extra 14% more performance from the 16% GPU and 8% memory clock advantages it has versus the reference hardware. The G70 GPU is little starved by memory bandwidth all other things being equal, on this evidence.
