    Thanks for the info. I'll have to keep that in mind. I read somewhere here that King of Interns was using a 980M, but he seemed unhappy with it.

    If your going to do a final gpu upgrade, then go all-in and get a 980m.

    The price gap between a 970m/980m is narrowing, and if your patient, you can snag a good deal. I bought a NEW, not used 980m, for $409 last month. I quickly sold my 970m for $350, so in the end the upgrade cost me $59 (ok it still cost me $409:D).

    The problem getting a 970m is (a great gpu btw), you will always be wondering what you could have had getting a 980m:(

    The 980m heat isn't the issue, it's the power consumption. You will need a dual psu, as a single 240w psu will trip constantly with any benching or any demanding game -that's been my experience anyway. That said, it's inexpensive and a very easy mod (esp. since a 240w psu only has 3 wires).

    You want to make the most out of the M15x and gaming today.

    I think it's pretty well established by other M15X owners that have tried the 980M that it runs way too hot in the M15X. Remember this laptop was designed for 75W cards, and the 980M has a TDP of around 120W. If you can get a modded vbios that undervolts it, then maybe you can tame it a bit, but otherwise I think the 970M is a better choice for the M15X.

    Yes I read his (KOI) post some time ago, however I have noticed his current signature includes a 980m w/ dual psu.

    I don't think you can go from one individuals experience with the card as the end answer. Plus I recall his was flashed with the Prema vbios, I used the one by svl7/johnksss.

    My 980m temps are not much different than I had with a 970m installed. Idle it's 36-45, gaming it's anywhere from 60s to 70s max.

    Does your 980m down clock itself? My 100w K5100m downclock to 80%, temp from 50 idle to 80 max load. It draw only 80w on max load.
    And how to you cool the back side vram?

    I haven't noticed any down clock. To cool the backside vram I just used 1mm Arctic Cooling pads, and the X bracket and screws that came with the card. There's not much space for much else as the depth of the gpu bay is very tight, some of the other X brackets with vram fins won't fit.

    That's awesome! Thanks for the feedback. Looks like I'll be getting a 980 then!

    I searched as much info as I could before buying the 980m. The only thread I have read where someone had a bad experience with it was KOI.

    Yet I found owners on 3dMark who had success:

    https://www.3dmark.com/3dm11/10019090

    https://www.3dmark.com/fs/4925460

    https://www.3dmark.com/fs/7596165

    Here is my 970m vs 980m (my username is not on the 980m, as I recently got the non-Steam version of 3dMark Advanced)

    Firestrike:

    https://www.3dmark.com/fs/11868560

    https://www.3dmark.com/fs/13799748

    3dMark11:

    https://www.3dmark.com/3dm11/12203257

    https://www.3dmark.com/3dm11/12411291

    Finally, before buying a 980m, I spoke to a seller on eBay who had a M15x with a 980m installed for sale and he claimed it never reached above the 70's on the GPU. I asked him how he installed it, and he said place 1 Copper Shim between the heat sink and gpu die (with TIM on both sides)....and voila!

    I'm not sure how much a difference the copper shim makes for temps, but that's how I installed mine and I don't have heat issues.

    I recall KOI's experience with idling temps were already ridiculously high, never mind benching or running intensive games. IMHO I think he got a bad card, or bad vbios.

    No problem, don't forget the Copper Shim^^. I have some extras (I could only buy a pack of 20 on eBay) I can send you a couple if you need it, just send me a PM.
