Does an i7 3930k at 4.4 Ghz bottleneck any dual GPU configurations?

[Cromulent]

I'm thinking of upgrading my GPUs at some point (I currently have 2 AMD 7950s in Crossfire) and was wondering if I should be concerned about my i7 3930k running at 4.4 Ghz would bottleneck any GPUs. I can't afford any more than 2 GPUs so I wouldn't be doing anything silly like running 4 GPUs at one time.

I might well wait until the next new GPUs are released as my current machine seems to be able to cope with anything I throw at it at 1440p resolution but I'm sure that won't last for long.

Any help is appreciated .

Very unlikely, unless the game in question is massively CPU dependant, in which case you will be running high enough FPS for the bottleneck to not even matter.

Cool. Thanks for the confirmation. I've never really known what the boundary is with CPU bottlenecks of GPUs.

Are there any tools that you know of that can help determine how much CPU time is being used versus GPU time? I'd be interested in something like that to see how much utilisation my machine is undergoing in certain games (particularly Crysis 3 and FarCry 3).

The beta version of msi afterburner will display cpu and gpu use in real time on screen, and log both over the course of a round.

Ah, up to this point here is only 1 core that is ~7-10% faster clock per clock than your core and it's the Ivy Bridge-E. Why would you think you processor is a bottleneck? In most cases it's actually an overkill. You can always overclock it more though, some SB-E processors go as high as 4.8-5GHz on air or AIO cooling.

Thanks, I'll check it out.

I guess I'm just not that sure on how my machine performs when playing intensive games. With the software advice above I think I'll spend some time doing some benchmarks to see how things are performing under the hood.

Yeah I don't see a 3930K being a bottleneck at all for a while yet
