There is always a way to improve the performance of your system by overclocking it. The Asus EN7900GS Top is already overclocked, compared with Nvidia's 7900GS reference board, by 140MHz for Core and 60MHz for memory.

We were curious to see if the card could handle even higher frequencies. Using RivaTuner v2.00 Final, we reached 621MHz for Core and 821MHz for memory.

We didn't see as much of improvement in the performance as we had hoped for. So, with an already highly overclocked card, overclocking is not recommended.
