So its not a good idea even if im overclocking? Also, its not just for games, also video editing and rendering.
For games, you'll see little difference, if at all. For video editing/ rendering however, the scenario is different for different programs. Some depend on CPU a lot while many can mak use of CUDA cores for GPU acceleration (provided you have Geforce GPU). Some egs are:
- sony vegas pro 11 will use GPU, it's GPU-accelerated
- Vegas 9 uses only the CPU for rendering.
- Premiere Pro uses the GPU for some effects on the video preview
- After Effect use GPU
- Power director 7-8-9 use CPU (90%) and if ran with richvideo hasGPU-accelerated
- Edius use CPU
So it depends, softwares which only use CPU will gain from OCing, how much? Can't say with concrete assureness, but it'll be a bit faster, say a couple seconds (faster) on 30 mins video rendering.
