Upgrade (?) from ATI HD8970M to NVIDIA GTX 680M

Hi everyone,
i experience some problems with ATI HD8970M, so I decided to replace it for NVIDIA GTX 680M. (previously I had 675MX). Please share any opinions - is ATI worth replacement? I heard a lot about ovclocking potential of 680M - does anyone have any experience with this particular card?
Thanks.

 

It won't be a huge jump. Any way to get a 765mx instead or even an 860m?

 

Nah, not on that laptop.

 

what´s wrong with it? next week a new CPU is coming - i7-3920XM

 

Clevo never put out a bios supporting anything past the nvidia 6xx or amd 7xxx (or 8xxx, same thing) series.

Check out a google search "p150em 780m", you'll see that it doesn't work at the moment, Prima is working on getting it up and running (he had it sort of working at one point but bricked a laptop/gpu)

edit, I think there was some confusion, I was responding to biggerx, going from a 8970m to 680m will work, though the difference won't be much, they're mostly as powerful but some games prefer amd some nvidia, at the very least you get physx.

 

Thank you for clarification. I decided that I will go for CPU upgrade first, see the results, and then decide what to do about the graphic card. 8970M seems to be a powerfull one, but it fails to work on my notebook (low results both games and benchmarks...)

 

I'm running a Prema BIOS on my Sager NP7338. It's pretty sweet I must say.
