Re: Will my Q9650 bottleneck my new EVGA GTX 275?
More CPU speed is always better.
If you're even considering overclocking, just do it.
There aren't really any down sides other than having to spend money on a better cooler.
Overclocking your CPU is incredibly useful in the rare situations where a game is extremely CPU heavy. You can always turn down graphics settings to reduce graphics load but few games give you any options to reduce CPU load. The more speed you have, the less likely you are to get frame rate drops when things get heavy (tons of AI, physics or geometry).
Also, when it comes one component blottlenecking another, there may be a general "sweet spot" with roughly balanced components but a CPU will always bottleneck a GPU in some situations and vice versa. It may be at 20fps or at 200fps. What's important is keeping your frame rates at a good level in the most situations possible.
