M17xr3 580m uprade to 680m or 770m

hi guys ive been here i while and i normally read through the posts with upgrading.
i've notice you guys know you stuff!

i'm on abit of a budget at the moment, but im not sure whats better i'm currently on a m17xr3 580m 3D but thinking of upgrading to the 680M or 770M which is better?
ive noticed the 770 is cheaper for reason

thanks in advance hope to talk soon

 

The 680m is better

 

With both options you will loose 3D. The 680m should be faster.

 

i never use 3d. i wish i got Sli instead

680m a big difference to the 580m

for example bf4 ultra fps?

 

General opinion is that the 680m with a decent OC is as good if not slightly better than a 780m. Probably in the region of 35% overall faster than a 580m (just going on the many people that have done this).

The 680m is also the most reliable (IMO) NV chip considering how long it has been around. Not seen a single failure . The heatsink from the 580m has been used by many 680m users without issue (research the pad layout, there are plenty of pics of this). Make sure you get the x-bracket for whatever GPU you go for - the original may fit but will not (probably) provide the correct pressure/clearance for the heatsink.

You will need a modified .inf file for the driver. Only machine/GPU combinations supported by the OEM are added into the nvidia notebook drivers .

Good luck

 

680M is way better than 580M: 90% faster. Let alone if you get a good OC on the 680M after flashing a modified vBIOS from here:
NVIDIA Kepler VBIOS mods - Overclocking Editions, modified clocks, voltage tweaks

 

It will be a noticeable upgrade.

 

another newbie question.
if my m17xr3 3d's 580m decided to pack its bags and die could i just purchase the 680 and replace with that or would i need a current oem supported card first?

 

Nope, any will work and the clevo versions actually overclock easier. You'll loose 3D with any 680m card, but 120hz will work - see my earlier post for more details. The nice thing about the 3D model is that you do not need a modded bios or make any changes to disable the on-board gpu, it's already disabled meaning that all you need is a modified driver inf file.

 

Yeah and it's the 120hz which is the nice part anyway

 

M680 with the tech inferno moded bios (with no extra vcore) and a good OC, Night and Day

 

ill also need thermal pads but i cant seem to find the right ones ? any recommendations links would be great
