The new G750 laptops carries the 700 series GPU. , now people reported that the 770m and 780M have identical GPU custom PCI currently in our G75 series (660M,670M,670MX). what does this mean ?

This means, you can upgrade your G75 laptops GPU to the 700 series from using one of the g750 gpus!

Of course the down side of this is you will gain an increasing heat output with the 780m. and the 770m compared to a 670mx is identical, a 670mx performs exactly as a 770m just 5% less. so for those with a 670MX, no need to obtain the 770m. but you can focus on a 780m

the biggest focus here is, if NVIDIA releases a MX series for the 770m and 780m. this will be greatly improved for our laptops. this reminds me so much like the G73 laptops getting so much upgrades even now up to 7970m

Now, the other thing is finding these cards sold seperatly will take couple month before third party sellers obtain them (Ebay users etc) I've found many cards of the 670mx, 660m whatnot on ebay by high reputation sellers.

just a heads up ! :)

You do understand that upgrading to the 7xx series will require more power to be drawn from the PSU which could make the GPU under-perform because the PSU cannot provide the power (which makes it useless to upgrade) or even worse, the PSU could melt or burn out.

It is always better to upgrade to a whole new machine than tinker with it yourself, after all you are not a professional engineer I believe.

I completely agree, but the fact that triggers me is that, if a old G-series (g73) can be upgraded up to a 7970m without having an issue with PSU, makes me believe this can be as well done right. now of course with Nvidia since ATI uses less heat output

but then again, this will be given a try by those guys who mod/upgrade almost everything on their laptops. hopefully we will see the result more in depth

I don't think the increase of power will be that big deal. the current 670mx can oc to up to 960mhz without volt increase. but im no engineer :P just optimist XD. hopefully i'd like to see this to be tried out first though!

I think the 770m is 30-50% faster than 670MX, you're thinking of the 765M. The 770M would be a great upgrade because the 180w psu should be fine, in fact a lot of companies use 180w psu's in notebooks with 780m and 47w quad cores, though there there is no oc headroom, the 770m should be fine or you could mod a 220w or 240w brick.

Those with a 670MX, an upgrade to the 770M is pointless. Why? Because if you just overclock the 670MX on stock 601-960/2600 without voltmod to anything around 1100/2600 with a modded vBIOS, you will not only be faster than the 770M by a huge margin but also a 680M to almost up to a 680MX.

The 670MX and the 770M are identical except for the clocks.

High OC'd 670MX > Stock and med OC'd 680M > Stock OC'd 770M > OC'd 765M.


Currently the G75VX (with upgraded 3840QM) is still faster than the JW and JX G750 models, which retail around the same.

But, what if you OCed 770m, wouldn't it give better performance?
