What do I need to install a gtx680m in a GT70 with a gtx675m?

Hello All,

I have a GT70 0ND 444US with a gtx675m that just died. I'd like to put a gtx680m in to replace it, unless someone has a better suggestion, but I'm not sure what I need. Looks like people suggest going with the MSI version over the 2gb ones, what about the heatsink, vbios, drivers, etc.? Anyone know what else I need? Thanks

 

You will need a heatsink that is compatible with GTX680 card. Did you purchase a MSI version of GTX680M? If yes, then you will not need a VGA BIOS.
Driver-wise, you can use the latest version from Visual Computing Leadership from NVIDIA without any issues.
If you aren't sure what 680M you are getting, then post its pictures on here.

 

Thank you for responding. I haven't purchased one yet but it looks like the 2GB version, which I guess are from Alienware/Dell, are a little cheaper and there seem to be a lot more of them. Is there a downside to buying the 2GB version other than messing with vbios? Do you know if the gtx675m heatsink I have will fit the gtx680m, I've been looking everywhere and unable to find an answer. I had been looking at this one: Dell NVIDIA GeForce GTX 680M Alienware M18XR2 M17XR4 Laptop Video Card 680M 2GB | eBay

Thanks again for your help.

 

You shouldn't expect any downside going with 2GB version because VRAM helps only when gaming at high resolution over 1080p so you shouldn't be concerned.
