The specs of the 670MX with 960 cores and 192 memory interface seems leaps and bounds more capable than the 660m.

Why is real world performance only slightly (15%?) better?

I realize the clock speeds are lower. Seems like they cripple it on purpose?!?!?!?!?!

Shows it significantly better?

yah i never realy understood how new cards come out clocked slower than older ones but i get told it has to do with the speed of the memory and other things. its all craziness to me lol. perfect world would be ati/amd hard ware with nvidia drivers, now that would be something to behold. just in my experience with nvidia graphics and ati. ill probrably get reemed for that but seems ati has the clock speeds and ram but nvidia has the better drivers and update more often.

Its newer technology (kepler) so the clock speeds are lower with better performance and less heat. I would think BF3 in 1080p with all settings on ultra getting 50-90 FPS is a pretty good improvement over the 660m.... On top of that my 670mx never gets above 62c even overclocked as far as afterburner will go...

What he said :) However, my temperatures stays around 65C

65 is still way below the melting point! Great gpu for the price I think. Overclocker it performs the exact same as my MSI with a gtx680 did.

......Overclocker it performs the exact same as my MSI with a gtx680 did.

Are you talking about the +135 core and +1000 mem only?

Or is there a BIOS mod for the g75vx that allows more than just the 135 core bump?
