Will i3 bottleneck a GTX860m?

[darthvadar]

I have the choice between the following:

i5 4210m, GTX 840m with 2GB DDR3, 8GB RAM (1600MHz), 1366x768 15.6" screen - £590

i3 4000m, GTX 860m with 2GB DDR5, 4GB RAM (1600MHz), 1920x1080 13.3" IPS screen - £591

i3 4000m, GTX 850m with 2GB DDR3, 4GB RAM (1600MHz), 1920x1080 15.6" screen - £577

The second one seems to be the best deal with the GPU but I'm not sure if the i3 is not going to allow it to perform. In order to get the i5 4210m within price range I need to downgrade to a GTX 840m.

Any information that would make this decision easier would be great.

Thanks

All 3 are dual cores with 4 threads, however, the i5 will turbo up to 3.2Ghz., and the i3's only run at 2.4Ghz.
it's a tradeoff. The 860m has better gaming performance than the 840m. If there's a bottleneck, the i5 would be less than the i3 obviously.

Yea the turbo would help with general use which is the only reason I'd pick that over the i3, but the difference between the GTX860m and the GTX840m seems to be huge especially since the 840m only uses ddr3 and the 860m uses ddr5.

I just need to know if the lower clock speed will cause the 860m to under perform.
