You would notice the difference, though I'm not sure if it's 100€ of a difference... perhaps 50€...

The 640m is significantly faster on its own and is basically the same silicon as the 650m, just clocked 100-150mhz or so lower.

It is likely you can OC the 640m to match the 650m without any playing with voltages and keeping an eye on temperatures.

the 7670m is the same silicon as the 7690m, clocked 125Mhz lower, you can see that this is still inferior to the STOCK 640m here:

I think it would be worth while to go with the NVIDIA option personally.

I have a slightly older laptop that has the 525m, which I clock to match the 550m with no problem. It is plenty of horsepower when coupled with my i7 to crank games at my panels native res. (720p). I have seen them get playable rates at 1080p.

The 640m is better. Should roast the proverbial ghost.

they still give it an 80%, but yeah, those high temps do not fill me with hope for OCing the GPU,

However it is possible to turn of turbo boost on the CPU when playing games (somthing which I discovered during my OCing research) with not much effect on overall FPS in games (actually if it allows a higher GPU OC they are often better).

It depends, I still would go for the stronger GPU, but then the first thing I would do is open it up and apply some MX-4 thermal paste to the GPU and CPU. The standard stuff they use is crap... If you are not that kind of user (who fiddles with the innards) then it may be more of an issue...
