    Hey guys so I have the option of getting a 970m for 200 AUD or I can get a 980m for 320-350 aud (depending on shipping). Which is the better upgrade for the m15x? I plan on doing some cooling mods so heat isnt as much an issue but I've seen some mixed views on the 970m vs 980m in the m15x and I'm wondering what everyone these days is recommending.

    Specs
    Cpu - i7 920xm
    240 watt adapter
    planning on adding either a 10 cfm or 13 cfm fan into the gpu cooler

    The 970M is the easier path, and is 85-90% of what you would get with a 980M.

    The 980M needs a dual psu mod (240w x 2) and the svl7/johnksss vbios.

    is it really 85-90% and do you 100% need a dual adapter even if not overclocking that heavily?

    if you are not using a 920/940xm, no. If you are, then yes.

    Yes the 970M is very close to the 980M. Unless you REALLY want the 10-15% gain then the 980M is not worth it, especially nowadays the 970M can be had for around $200 range, the 980M is still pricey,

    Even if you don’t OC, you will need a dual psu (not for 970M). 980M/920xm combo just takes too much power. You will either get major throttle, or you will get psu tripping.

    Ah ok, sorry for all the questions just wanna make sure I get the best deal :p. So i can get the 970m for 150 USD or the 980m for 230 USD what would you go for? I have the 240 watt adapter is this definitely not enough for 980m (120 watt) and i7 920xm (75 watt) ?

    I would suggest the 970m. Of course it depends on how high you are planning push your graphic settings on your games.

    I'm hoping more I can achieve higher frame rates as I managed to get an 120hz overclock from my screen, but if the performance is going to be near the same I guess the 970m is a wiser choice. I intend on modding a 13 cfm fan in for the gpu so heat hopefully shouldnt be an issue

    For that price I recommend the 970m for sure.
