E6750 to 3.2, worthwhile OC?

It would be noticeable if you run intense applications such as games. It will not be noticeable if you only run firefox.

It really depends on what you plan on doing with your computer. If its a CPU intensive task for transcoding or graphics rendering, or games it could give you a boost. For everyday tasks, there won't be a big difference.

My advice would be to Do a light OC like 3.2GHz, and see if you notice a difference in speed. For that, you should be able to keep it at stock voltages, or a small increase, maybe to around 1.3 or 1.35V. I'll let someone else help you with the voltages, because I don't have experience with that chip. But just keep the voltages as low as you can without the system crashing when you boot or run an intensive task.

cool, thanks. yeah i play COD4, TF2, and soon SC2. i ordered a radeon 5770 and so i'm hoping i will be able to take on all 3 games easily with max settings. i will probably try the 3.2 after i get the 5770 and see how all the games (except SC2 obviously) run.

so what do i need to do on OC'ing this...i have read the OC guide, but really i am wondering if i punch it up to 3.2 (heard 3.6 is a pretty common OC for this chip), what do i need to set the RAM to, vcore? any help is appreciated.
