How much performance difference in i5 2500K overclocked ?

post #1 of 16
Thread Starter 
How much does it is increase in % for performance for i5 2500K overclocked to 4.0 GHz in:

Video Rendering ( Sony Vegas 9.0 )

3D Rendering (Blender and 3Ds Max)

Games ( Every modern now )

Also will less temperatures make the performance even greater ?

Probably not much. 4.0GHz is like a microscopic overclock for the 2500K.

When overclocking the 2500K or 2600K (and now the 2700K), we are overclocking the Turbo Ratio. This means that it starts at 3.7 GHz for the 2500K which means that 4.0GHz is actually just a 300MHz overclock. This is why it's possible to achieve 4.7 to 4.8 GHz with air cooling.

If you're going to stay at 4.0GHz (which would be a shame), then yes. However, which motherboard do you have?
