    Youre better off staying with 8700k to be honest, 9900k runs way too hot (in a desktop with ample cooling, I can't imagine how hot it would get in a laptop chassis with 120w heat pipe) and it's not a matter of inadequate cooling or not being delidded. Derb8uer did excellent work showing that the die thickness is behind the temps:



    The 9900k is twice as thick as 8700k (9:16 mark), and der8auer believes that that's why it runs so hot.

    When you look at gaming benchmarks comparing both 8700k and 9900k both running at the same freq. the 9900k is not actually faster because of unavoidable thermal induced throttling coupled with the fact that nearly all games do not care about core count, but only IPC and freq:

    Ultimately youre wasting your time, you already have the best CPU for gaming.

    I'd only advise a 9900K for desktop owners, sure you can pop it in your Clevo, it'll burn your house down and throttle to below base clocks, but it'll still run if you're just after 8c/16t. Even in a desktop, its only marginally faster in gaming loads. However, in workstation-type multi-threaded loads, in scenarios's where you can cool it, it beats out the 8700K/2700X by a decent bit.

    Another thing that has just sprung to mind, can you run two 1070 in SLI in Optimus?

    There is a guy on Ebay selling a M18x R2 with a 1070, but only single, and when I asked said he was sure two would work as well.

    Has anyone tried dual 1070 in M18x R2 in Optimus?

    It’s not possible at all. There’s not enough bandwidth for both GPUs and the IGpu together. That guy is talking straight crap to you lol.

    That's what I thought too based on what I had read here, but he planted a seed of doubt:)
    He sells modded M18x laptops on Ebay, Transylvania laptops or something he is called, so one would assume he should know what he is talking about!

    Oh the romainian! He charges rip off prices though and I don’t think he knows the details that people like @Khenglish know.

    Yup, him, I would never buy a M18x R2 with a 1070 for £1.9k lol.
    Ok, so no 1070 SLI in SG mode...crap, I was hoping I would buy one SLI capable 1070 now, and then in a few years buy another to keep the system relevant but hey ho. I might just have to settle for the same plan but with a 980m instead.
