Will a i7 920 bottleneck a GTX 680?

Will a i7 920 bottleneck a GTX 680 and how severe would the bottleneck be? If it will bottleneck, how hard will I need to overclock it before I see little to no bottleneck?

If it's at stock then yeah I would clock it to around 3.6GHz minimum for no bottleneck. Don't think at stock it would bottleneck a single 680 but I'd still clock your i7 above 3GHz definintely.

3.6Hz can be achieved with the stock cooler and on stock voltages for most boards and cases with reasonable airflow. Just keep and eye on temperatures. Shouldn't see much/if any bottlenecking then.

Is 3.6 just a guesstimate or are there any articles you could show me that test it?

Thanks for the input

I dont know of any articles that compare clock for clock Vs possible bottlenecking of a 680.


Like I said, even at stock I doubt it would bottleneck a single 680 but I would still clock it all the same. 3.6GHz is a nice middle ground where it's not pushing the CPU but it's also giving it enough grunt. Clock speeds under 3.0Ghz can suffer at times.

Just buy the 680 and OC the CPU to 3.6GHz

I can confirm is doesn't in BF3, 99% in single card mode. But when I enable SLI I am not so sure.

I think it's a mixture of CPU limit and driver support for bf3.
