    Yeah, but I have a very bad experience with these 640/650M slim (more or less) laptops. Hot as crazy, can't keep performance for long, will shut down. They look amazing on paper, I give you that.

    I would want laptops to be really laptops, not legs burning machines with great specs, but unusable.

    I agree that 675MX would be a huge thing for Asus on gaming market since a lot of people want to buy an Asus, but the performance is not quite top notch.

    My G75 with 670M is just fine performance wise and I will keep it for at least 1 year. Other things matter more and I think Asus should fix those first.

    If I get some time i'll snap some photos of the PSU just to give everyone some perspective.
    Your PSU data is wrong. It is nowhere 300W, and the power requirements between 670M and 680M are pretty much identical.

    Alienware M17x R4 (680M): 240W
    Sager 9150EM (680M): 180W
    Sager 9170EM (680M): 180W
    MSI GT70 (680M): 180W
    Asus G75 (670M): 180w
    Asus G55 (660M): 150W

    Yes I think pretty much everyone would agree that a 675MX would be the only right move from Asus. Well, they could make two hardware systems, one with 670MX and one with 675MX.

    Yeah I double checked that and you are correct.

    It might be a price point issue then.

    We must wait for g75vz to have 675mx on board

    So if my G75VW is still within warranty period to be able to be returned for refund, should I get it refunded and wait for the VX?

    Is the jump between the 670m and the 670MX that significant?

    670MX will be around 18% (estimation from me since no numbers exist yet) faster than 670M. 670MX will run much cooler than 670M. 670M is an overclocked 570M, meaning you can`t overclock it so much. 670MX have a huge overclocking potential.

    675MX is probably 35%-40% faster than 670M, pretty much identical with the heat of the 670MX and have much better overclocking potential than 670MX due to the fact it have wider memory bus, which again means it can deal with the data much better than the 670MX.

    Here are some 675MX numbers if you want to see for yourself

    Are you seriously saying that the memory interface size has a effect on the overclocking potential of a gpu?


    Ok flat out Kepler overclocks higher then fermi every time. I got a GTX 660m that pulls 1,350 on the core every day show me a GTX 670m that can do that. My GTX 670MX pulls right now 1,225 on the core and i can tell you at this clock the GTX 670mx pounds the 670m into the ground and beats it to a bloody pulp and i got the same numbers as a stock GTX 680m with that MX overclocked. That being said this card should have more overclocking headroom and i think the early drivers are affecting it because they are kind of crappy.

    So lets explain gpu memory interfaces for 40,000.000 time.

    GPU memory interfaces allow the GPU to address more memory per cycle. Now memory runs at its own speed so to get bandwidth you need to mix the right mix of speed and interface. Example 128bit interface with some really high clocked fast ram is about equal to 256bit with slower clocked ram. The memory interface has nothing to do what so ever with how high you can clock your gpu.

    Now the reason why my GTX 660m "128bit" beats GTX 670m's "192bit" Is from my core being so high, My memory being so high and the memory timings on my 660m.

    Memory bus have an EXTREMELY impact on overclocking potential.
    There is a limit on how high you can overclock your GDDR5, which means there is a limit on how high memory bandwidth you can have, which means there is a limit on how much information you can process at a certain GPU clock.

    Stock clocks the 670MX have a memory bandwidth of 67GB/s. 675MX 115.2GB/s. Both running @ 900MHz. Already here the 675MX have a HUGE lead. I`ve overclocked the 680M myself, I can get the memory up to 1200MHz-ish.
    Increased memory speed means higher heat means more wear on the memory means possible unstability.

    You can already see yourself today that Nvidia have crippled the 670MX with 192bit bus. Why? Because already at stock clocks, the 675MX is beating the 670MX by 20%! Thats with the exact same GPU clock...

    You could overclock the memory on the 670MX to reach 675MX stock scores, but you can overclock the memory on the 675MX to allow better scores again when overclocking the cores. 670MX would be hindered by the small memory bus when overclocking high. The GPU wants to process as much as possible, memory does not allow that.

    As for your 670MX (do you already own it?) reaching stock 680M scores, I call BS on that. You would have to overclock the cores and the memory by a huge number to accomplish that.1200MHz? LOL yeah right. Bull. Not to mention that you probably need a custom VBIOS with higher voltage.

    Post your screenshots. Prove me wrong. I call you out
    (PS: Don`t post "Performance" scores of 3Dmark11 or Vantage. Post "Extreme" preset scores where you will see the memory bandwidth come to play)

    I hope the price is reasonable! May sell my G55 and pick up a G75VX... G55 performance is a little underwhelming

    The 680M won't fit in the G75. Won't fit. The 675MX is an underclocked 680m. Thererefore, the 675mx won't fit in the G75. Won't fit is won't fit.

    Asus ROG is NOT about having the heaviest, hotest, loudest, highest performance notebook you can have. If you want MOST powerful, and hot, and loud and heavy, go elsewhere. Asus G75 is about bring portable gaming to the masses. $1150 G75-BBK opens up a much, MUCH wider market, and makes portable gaming accessable to way more folks than $2000 680M from another market. Many customers want cheap. Many customers want truly portable gaming. Running around airports with a 680M heavy beast is a PITA. G75? much nicer.

    SO, what does the customer need to give up for cool, cheap, and light? What games will the enthusiastic G75 owner have to give up at highest detail in order to get cheap, cool and light?

    NOT so many games, 3 maybe, at ultra settings in 2012? with the 670MX none at current time? Is there ANY game the 680m can do at ultra the 670MX can't do?

    I want cheap and light. Asus has that. Now, if I was really into high quality gaming maybe I would like at an MSI with a 680M and a 3D screen ... oh snap, Asus has 3d screen, MSI doesn't.

    Stop with the "Asus doesn't have close to state of the art". Go look at the performance specs of the 670mx, its still going to be one of the top 4 available cards, yes, not top 2, but, seems pretty close to state of the art.
