Of course this GTX 285 AMP! is sold as a 'pre-overclocked' card but just for the sake of it we'll see if we can get any more out of it.

I used NVidia's own onboard control panel to adjust the GPU clocks - it managed the following clocks:

Core Clock - 702MHz to 739MHz
Memory Clock - to 1296MHz to 1349MHz

I then tested the performance increase in 3DMark06 and Vantage:



Then i tried some of the games already benched.




As you can see there's a fairly healthy increase across the board. If you ever need the extra performance it's nice to have it available.
