Bottle Necks?

can a video card prevent overclocking of a CPU??

Prevent overclocking? I haven't seen that. Although it is possible that adding a second video card can put enough stress on the northbridge to reduce overclocking potential. Generally when we talk about bottlenecking, we're referring to the phenomenon of one particular component in a system being underpowered and causing the rest of the system to perform below its potential.

But when they mean by bottleneck is usually less than a couple % slower and usually not a massive bottleneck like some people try to make them.

Yup, what 2 and 3 said.

thanks.. i was just curious because my friend was talking about a more powerful GPU making it easier to overclock.. i guess that its a false statement thanks for the info

The bottleneck can be very large depending on the application and on the specific hardware in question.

No, that's complete BS.

the motherboard will be the most limiting factor of overclocking your cpu...and cooling ofcourse......

There ARE times where the onboard video has held some motherboards back from overclocking well. By adding a video card into the PCIE slot you can then get a greater overclock out of the CPU.

However, if you originally added a GTX260 in the slot you're not going to get a better overclock by later adding a GTX280.

Hope that makes sense.

Im not 100% but most cores these day Will max out a Mobos FSB, If set proper.

As for GPU causing a lower overclock... Smack your friend with a BAT.
